In the UK, we've been dealing with multiple unseasonable heatwaves, and if it's taught me anything, it's that hydration is important — and so is keeping your drinks at the right temperature. It's a small thing, but many times over the last few days, I've taken a sip from a bottle in my bag and grimaced, as my cheap non-insulated, single-layer metal screw-top bottle just isn't keeping anything cool.
Fortunately, thanks to the Amazon Prime Day deals, I'm coming prepared next time. I'm ordering myself a Yeti Rambler 42oz Straw Mug. Yeti are the gold standard of keeping things cool (and hot), and Amazon is doing some particularly good deals on their Tumbler shape right now.

In the US, you can get the Yeti Rambler 35oz Straw Mug at Amazon US for $29.40 (was $42) in its White and Papaya colors. In the UK, you can get a slightly larger discount: the Yeti Rambler 42oz (1.5L) Straw Mug is available at Amazon UK for £29.25 (was £45) in Navy and Key Lime colours.
Check out both deals below:
Today's best Amazon Prime Day Yeti dealsSave 30% on the Rambler Straw Mug's 35oz size in Papaya or White colorways. This is a cold drinks bottle for life, as Yeti famously over-engineer their products and back them up with a five-year warranty. Dishwasher safe. Also in White. View Deal
Save 35% on the larger 1.2L bottle in the UK, in White, Navy or the Key Lime colour opposite. Yeti makes their products to last, and their cooling technology is second to none. The straw is clear plastic so you can easily spot any build-up affecting taste, and the product is also rust and puncture resistant.View Deal
The Yeti Ramblers are ideal for the gym, but they'll really shine on a long commute or car trip too, as you can pop a cold drink in them, head out the door on your way to work, and still be sipping refreshed at midday. I've ordered the larger 1.2L version because, as a fitness writer, I'm apparently supposed to be keeping myself hydrated.

- X-VPN has added dedicated Soccer servers aimed at World Cup viewers
- The servers cover six countries, chosen based on language preferences
- The launch arrives as streaming demand and server congestion peak
With the 2026 World Cup already underway across the United States, Canada, and Mexico, X-VPN has rolled out a server line built for one job — streaming football matches.
The company has launched what it calls a dedicated Soccer 2026 server line across six countries: the United Kingdom, Ireland, Brazil, Austria, Poland, and the Netherlands.
Plenty of people already reach for the best VPN to follow their team when they are travelling or stuck behind a regional blackout, and the broad strokes here are familiar.
What is different is the framing: a seasonal, event-specific line that is meant to be quicker to navigate than a general world map of servers. If you have ever wondered whether you even need a VPN to watch the World Cup, this is X-VPN's pitch for one.
What X-VPN's Soccer 2026 servers actually do(Image credit: X-VPN)Instead of a generic country list, the Soccer 2026 line points you toward locations tied to the tournament's free and regional broadcasters.
Several of the six countries map neatly onto the platforms fans already use to watch the World Cup for free, with the UK in particular covering BBC iPlayer and ITVX. The selection is built around language and viewing preferences rather than raw server count.
On availability, X-VPN says initial support has been announced for iOS, Windows, macOS, and Android, with Apple TV and Android TV support planned. That last part is worth flagging, since the living-room devices most people actually watch football on are still on the roadmap rather than live today.
Why streaming-optimized servers matter during the World CupLive sport is one of the hardest things to stream well. The feed is real-time, it eats bandwidth, and a small amount of lag can mean a goal alert buzzes your phone before you see the ball hit the net.
The flip side is congestion: when too many users pile onto the same server, speeds drop, which is exactly the risk during a simultaneous global kickoff. Grouping servers around a specific event is, in part, an attempt to manage that load.
A server tuned for streaming is really about three things: speed, stability, and not landing on an overcrowded connection when millions of other people are watching the same knockout tie.
None of this removes the basics. If you are watching on stadium, fan-park, or hotel Wi-Fi, your local network is often the real bottleneck, and a few settings tweaks to keep your connection fast in crowded environments will do as much for your stream as the server you pick.
The tournament runs from June 11 to July 19, 2026, and is the first 48-team World Cup, with 104 matches in total. That is a lot of football, a lot of late nights for some viewers, and a lot of demand hitting broadcasters at once.
A server line built for exactly this window makes it easier for more people to watch the matches they're interested in, and with the regional complexities and expenses involved with sports streaming, this is always a good thing.
I’ve been reviewing audio gear at TechRadar for years now, and there’s nothing I enjoy sinking my teeth into than a brand new pair of noise cancelling headphones. I’ve tested more than 15 pairs so far, some of which have been mind-blowingly good, and some…less so.
In a highly convoluted market, it can be tough to pick out just one pair of headphones to buy, but today, I’m here to narrow things down for you. I’ve picked 4 of the best noise cancelling headphones that I’ve tested so that you can get great bang for your buck and enjoy your tunes without compromise.
There are options for a range of budgets here, from a top-class budget-friendly set all the way up to a premium pair that’s sure to bless your ears. Curious to know what made the cut? Scroll on down and discover my top picks.
1. The budget big-hitter: 1More Sonoflow Pro HQ51(Image credit: Future)I’ve raved about the 1More Sonoflow Pro HQ51 plenty of times, and for good reason. These headphones almost feel too good to be true — and on multiple counts.
Firstly, they’re incredibly cheap. They’re regularly available for less than $90 / £90, making them far more affordable than models from the likes of Apple and Bose. But that low price-point doesn’t come at the cost of quality. The Sonoflow Pro plate up surprisingly strong sound quality, with rich bass, clean mids, and controlled highs. They even have LDAC support for higher-res Bluetooth listening, which is a great feature for a product at such a budget-friendly price-point.
Another area these headphones excel in is ANC. Sure, you’re not getting Bose QuietComfort Ultra levels of noise-nixing, but they’re effective at dulling external sounds right across the frequency range, making them a nice pick for commutes or daytime walks. Pair that with an extraordinary 100 hours of battery life (65 hours with ANC on) and a sleek look, and the 1More Sonoflow Pro HQ51 are an easy recommendation.
2. The best all-rounders: Sony WH-1000XM6(Image credit: Future)If there’s one pair of noise cancelling headphones I’d recommend to everyone, it would be the Sony WH-1000XM6. These are the headphones that I use every single day, and in my eyes, they’re the perfect all-rounders, delivering class-leading ANC, stellar sound, and an ingenious design.
Let’s start with ANC which is so good here, that it even beats out Sony’s newer, more expensive headphones, the Sony 1000X The Collexion. The XM6 make use of Sony’s QN3 processor, which harnesses the power of 12 microphones to block out noise from your environment, and while they’re great across the board, they’re especially good at keeping low-end sounds away, even outdoing Bose in this area in my view.
Yes the Bose QuietComfort Ultra Headphones Gen 2 are arguably a bit better at banishing higher-pitched sounds, but we’re talking about fine margins here. And I’d pick the XM6 over their Bose rivals every time for one key reason: they sound a good deal better, in my view.
The XM6 were co-designed with leading mastering engineers for a studio-inspired sound, and take a more balanced approach than their predecessors, the still excellent Sony WH-1000XM5 and Sony WH-1000XM4. They still sound nice and punchy however, and their tight and dynamic sound is a joy to behold. Again, LDAC is here if you want a more detailed listen — as is 3.5mm wired connectivity.
On top of this, the XM6 offer top-tier touch controls, scene-based listening, a ten-band equalizer, and an effective transparency mode. In our best headphones guide, we ranked these as our best overall pick, and I’d strongly recommend you try them for yourself and find out why.
3. The noise-nixing on-ears: Marshall Milton ANC(Image credit: Future)Here’s something a little different. Yes, the recently released Marshall Milton ANC aren’t like any other entries in this list, as they’re actually on-ear headphones. The Milton ANC look to blend the iconic look and feel of the Marshall Major line with the noise cancelling prowess of the Marshall Monitor III ANC, and what do you know, they pull it off to perfection.
When I reviewed the Marshall Milton ANC, they honestly outstripped my expectations. See, I’m not generally a fan of on-ears, as I tend to find them uncomfortable, and their tendency to leak sound usually means I’ll just reach for my over-ears instead. But the Milton ANC are by far the comfiest on-ears I’ve ever tested, with a generous, flexible build — and they honestly sound great too, with less leakage than some rivals I’ve tested.
Out of the box, the Milton ANC are pretty bass-heavy, which will appeal to a lot of listeners I’m sure. However, the Marshall Bluetooth app provides an equalizer for toning things down a bit if you want a more even spread across the frequency range. Unlike previous Marshall products, these also feature LDAC for higher-res listening, but you’ll also get USB-C audio passthrough for lossless playback.
What’s more, the Milton ANC feature a colossal 80 hour battery life (with ANC off), a soundstage mode for more immersive listening, Auracast connectivity, and a gorgeous retro-style design. They’re also made of 42% recycled materials, and you can get replaceable parts in the situation that they break, which makes them feel like a worthwhile long-term investment.
OK, the ANC is a little limited as a result of the on-ear design, but they still restrict outside noise pretty effectively, and I’ve happily used them on trains and buses with very little distraction from whatever I’m listening to. So, if you want the flexibility that on-ears can offer with the benefits of noise cancelling, then the Marshall Milton ANC are without question my top choice.
4. The premium pick: Bowers & Wilkins Px7 S3(Image credit: Future)Last and most definitely not least, we have the Bowers & Wilkins Px7 S3. If you want something that feels, looks, and sounds truly premium, this is it — this is what you’ve been looking for.
The first time that I put these headphones on, they took my breath away. They conjure up a sense of space that few rivals in this price bracket can muster, with incredibly immersive, almost three-dimensional sound. Bass is full-sounding, extends deep, and hits with striking agility. Mids are brilliantly defined, and vocal separation adds a layer of nuance that will keep you coming back for more and more. And the treble is vibrant without sounding uncontrolled or fatiguing.
And the Px7 S3 almost look as good as they sound, with an enticing faux-leather, metal, and fabric combination. They even come in an eye-catching range of colors, with Indigo Blue and Canvas White being my personal favorites. Mix in aptX codec support, much-improved ANC (compared to their predecessor), and a comfortable fit, and you’re getting a brilliant overall package.
While their sibling, the Bowers & Wilkins Px8 S2 is the superior pair of headphones, they are far more expensive than the Px7 S3, which I think are fantastic in their own right, and I’d recommend with confidence.
Microsoft has just announced that the price of the Xbox Series X and Series S consoles will increase "effective August 1, 2026" in a post on Xbox News Wire. Specifically, the company says that "The price of Xbox consoles will increase by US$100 for 512 GB models and US$150 for 1 TB models. We will also be sunsetting our 2 TB model."
We don't have confirmation on what this will mean in countries outside the US, but we know there will be changes worldwide; the question is how much.
This will make the prices of Xbox consoles in the US as follows:
New Xbox console pricingOld price
New price
Xbox Series S 512GB
$399
$499
Xbox Series S 1TB
$449
$599
Xbox Series X 1TB All-Digital
$599
$749
Xbox Series X 1TB Disc
$649
$899
So the Xbox Series S now costs the same as the Series X used to, and is the same price as the PS5 Digital Edition currently costs (though we'll see if that changes again too…).
Fortunately, you have a chance to beat the price rise at the moment — if you're in the US, Walmart has a great discount on the 1TB disc version currently.
The Xbox Series X serves up stunning graphics and super smooth performance — this is a great discount for the disc version, and may sell out quickly now that the price rise has been announced.View Deal
We're getting into a real crunch point when it comes to price rises caused by the AI-driven memory crisis.
Apple has just announced a huge suite of price rises, having resisted as long as possible, and the price of the Steam Machine shocked people who were hoping for something more console-level — but Valve says the memory companies had them over a barrel, basically.
It's hard to say if the price rise coming just before the GTA IV launch is a cynical move by Xbox, or if letting us know six weeks in advance, during a sales event, just after GTA VI pre-orders went live is doing us a favor — I'm inclined to lean towards the latter.
I test over a dozen coffee makers every year, and I've discovered that great espresso machines don't have to be expensive. In fact, there are some truly excellent options around that perform just as well as pricier models, without burning a hole in your wallet. Here I've put together a list of my three top-rated budget espresso machines — and if you're lucky, you might find that they're even cheaper right now for Amazon Prime Day.
- Check our the full Amazon Prime Day sale
All these espresso machines are from reputable brands (De'Longhi, Breville, and Philips), so you can be confident that you're getting a well-made appliance with proper after-sales service too. Whether you're looking for a simple manual machine, or something that will handle the entire brewing process from bean to cup, I've got you covered.
1. Philips BaristinaFutureFutureFutureFutureFutureFutureEveryone who knows me will know that I'm obsessed with this little espresso machine. You see, usually bean-to-cup machines are expensive and messy, but not this one. Its 'one swipe' brewing means you never have to weigh anything; just insert the empty portafilter handle and the machine will do the rest, grinding and tamping the beans, then whisking them over to be extracted.
During my tests, the coffee it produced was consistently well-extracted and flavorsome, and because the brewing process doesn't happen inside an enclosed case, as it does with most automatic coffee machines, you don't need to worry about things getting damp and dirty inside. The Baristina is as easy to clean as a manual coffee maker, but doesn't require any barista skills. Ideal if you're looking for your very first coffee maker, or want to upgrade from pods to fresh beans.

2. De'Longhi Dedica DuoFutureFutureFutureFutureFutureFutureAnother of my favorite compact coffee makers, the De'Longhi Dedica Duo is the right machine if you're willing to try honing your own barista skills, and want a manual espresso machine rather than an automatic one.
The Dedica Duo is super affordable, and you're likely to find it even cheaper for Prime Day. Most espresso machines in this price bracket are quite poorly made and deliver inconsistent results, but De'Longhi has a reputation to maintain, and the little Dedica Duo is just as solid and reliable as any of the company's premium coffee makers.
Read our full De'Longhi Dedica Duo review
3. Breville Bambino PlusBreville, edited by GeminiFutureFutureThe little Bambino Plus is often recommended as a good espresso machine for first-timers, and with its easy controls, small but solid build, and entry-level price, it lives up to that reputation. One of my favorite features here, which you won't find on either of the other coffee makers, is its auto milk wand, which lets you choose from three different milk temperatures and three milk texture settings. You can steam your milk manually if you prefer, but it's a great option that lowers the barrier to entry for beginners.
Like the De'Longhi machine above, the Bambino Plus is able to sustain the pressure and temperature necessary for consistently extracted coffee every time, despite its small size. You won't need to worry about your coffee suddenly tasting different for no apparent reason, as you do with some affordably-priced espresso machines. A solid and dependable little brewer.

- Samsung has announced the Galaxy A27
- This budget phone has a faster chipset than the A26 along with a refined design and an improved selfie camera
- However, it has worse water resistance and fewer megapixels in its ultra-wide snapper
Samsung has just launched a new budget phone, with the Galaxy A27 arriving to take the place of last year’s Samsung Galaxy A26. But while there are some worthwhile upgrades here, there are also at least two downgrades.
Most notably, while the Galaxy A26 has an IP67 rating, the Galaxy A27 is instead stuck with a lesser IP64 rating, meaning it’s less water resistant.
At least one of the cameras also looks to be a downgrade, as while both phones have a 50MP wide camera and a 2MP macro one, the Galaxy A27 pairs those with a 5MP ultra-wide, whereas the Galaxy A26 has an 8MP ultra-wide snapper.
Looking purely at megapixels, the front-facing camera may seem a slight downgrade too, as it's 12MP on the Galaxy A27 and 13MP on the Galaxy A26. But overall, this is probably actually an upgrade, as Samsung claims the new camera can capture “a wider range of brightness and richer colors” for more natural-looking selfies.
(Image credit: Samsung)A faster chipset and smaller bezelsAs for things that are clear upgrades, there’s a more powerful Snapdragon 6 Gen 3 chipset, a punch-hole camera in place of a notch, and smaller bezels. The Samsung Galaxy A27 also has improved AI capabilities, such as multi-object recognition in Circle to Search, and more precise results from Object Eraser.
Beyond that, most of the specs are the same as last year, including a 6.7-inch 120Hz screen, up to 8GB of RAM, up to 256GB of storage, and a 5,000mAh battery with 25W charging.
The Samsung Galaxy A27 also runs Android 16 and comes with the promise of six generations of Android updates and six years of security updates.
It’s launching in the UK on July 3 and the US on July 14, starting at $349.99 and £319, respectively. We don’t have official confirmation of whether it’s coming to Australia, but reports online suggest it will also launch there on July 3, starting at AU$499.
It will be sold in black, blue, light green, and light pink, but not all regions will necessarily get all of those colors — we know, for example, that in the US, it’s only going to be sold in black.
If I were a 'brand guy', my brand would probably be Anker. Almost my entire home office runs on the company's power and audio gear, and has done for years now (ever since I got my paws on the original Soundcore Q20 headphones).

Robot vacuum deals this year aren't quite as good as they used to be; as interest wanes due to lofty list prices and continued difficulties to raise the bar of cleaning quality, robovacs can be a tough sell. That being said, some are outstanding, and this year for Amazon Prime Day, the best robot vacuum I've personally tested is on sale.
• See all of today's best Amazon deals
Right now, you can save big on the Dreame X50 Ultra Complete, which launched at $1,799 last year before its price drop to $1,149.99; and right now it's $884.99 at Amazon. In the UK it launched at £1,199, then dropped to £749, and it's now £659 at Amazon.
While the list price drops contribute massively to the savings, a $265 / £90 discount is still noteworthy. That being said, it's still an expensive purchase, and if you don't need an "all the bells and whistles" robovac, you could be better off with one of the below models under $500 / £500.
Best Dreame X50 Ultra Complete deal todayDreame's X50 Ultra Complete was the best robot vacuum I tested last year, earning it a near-perfect 4.5-star rating in my review, and at this hugely discounted price, it's the deal to beat this Prime Day in the premium robovac category.
Easily one of the most feature-laden robot vacuums I've ever used, the Dreame X50 Ultra Complete isn't messing around when it says it's "complete". From threshold-climbing legs to a retractable sensor puck, its extending side brushes to the self-cleaning base, there's little left to the imagination with this full package robovac. Plus, it offers powerful 20,000Pa suction, and during testing its battery lasted around 90 minutes. View Deal
I spent months testing the Dreame X50 Ultra complete, and was consistently impressed with its performance and high-tech features. In addition to ample 20,000Pa suction and 90 minutes average battery life, it's incredibly well equipped for cleaning; extending side brushes, a self-cleaning base, and not to mention its threshold-climbing legs to a retractable sensor puck.View Deal
If you don't need something as high-specced as the Dreame X50, check out my top three picks below, which have all been tried and tested by team TechRadar.
Best budget-friendly alternatives in the USRecord low: A different model from Dreame, the L40 Ultra scored 4.5 stars in our review. Its cleaning base is a little bulky, but this combination mop-and-vac model offers impressive cleaning with plenty of on-board smarts. Its navigation technology is solid, obstacle avoidance is great and it offers good pickup on pet and human hair. This is its lowest-ever price. View Deal
Record low: At its lowest-ever price, the roborock Q7 M5+ is a steal this Prime Day. We scored the base model 4 stars in our review, praising its impressively strong suction at a budget-friendly price, and this M5+ model comes with an auto-empty base. It's less feature-filled than other robot vacuums on this list, but still a capable cleaner with solid navigation, including over tall thresholds thanks to bouncy suspension and chunky wheels.View Deal
While it's $30 more expensive than the record-low price from a few years ago, this is the cheapest we've seen this robot vacuum since. We scored the standard, non-Max model 4 stars, praising its decent dust and dirt pick-up, simple features and great value-for-money; this slightly more powerful version should be good enough for your day-to-day cleanup.View Deal
Best budget-friendly alternatives in the UKAt 50% off this is just £5 shy of a record-low price on a solid robot vacuum we scored 4 stars in our review. With specs typically boasted by robot vacuums twice the price when it released back in 2024, it's no slouch when it comes to vacuuming and mopping, handling pet hair and dirt on various floor types well. It won't clean up spills and stains super thoroughly, and Shark's software leaves room for improvement, but it's a solid robovac nonetheless.View Deal
Record low: At its lowest-ever price, the Dreame L10s is a solid robot vacuum we scored 4 stars in our review. It can automatically detect various floor types to determine whether it should vacuum or mop, mapping is impressively accurate and it's self cleaning; albeit a little loud in doing so.View Deal
With impressively strong suction and a very approachable price point, we scored this model 4 stars in our review. It's not quite as feature-filled as other, more recent and premium robot vacuums on this list, but still a capable cleaner with solid navigation, including over tall thresholds thanks to bouncy suspension and chunky wheels.View Deal

Well, we saw this coming: Apple just announced major price hikes across its product portfolio, meaning popular devices like the MacBook and iPad are getting more expensive.
• Browse the full Amazon Prime Day sale
In fact, they’ve already gotten more expensive — the Apple store went offline this morning and reappeared an hour later with the new product prices. These increases are a response to “an extraordinary surge in demand for memory and storage,” Apple confirmed to TechRadar, adding that “we have shielded our customers from these increases so far, but we have now reached a point where we need to begin raising prices.” Sigh.
As TechRadar’s Phones and Tablets Editor, I’m particularly irked by the fact that the iPad Air now starts at $749 / £749 — that’s a $150 / £100 increase over its former $599 / £599 starting price, which taints its appeal as an affordable all-rounder.
The iPad Air has long been my go-to tablet recommendation for most people, but at this new price, I’m more inclined to recommend the iPad 11-inch (2025), which continues to start at a comparatively cheap $349 / £329.
The good news among all this doom and gloom is that Amazon’s annual Prime Day sale is happening right now, and several excellent Prime Day iPad deals are live in both the US and the UK. The iPad Air is among these discounted Apple tablets, so if you’ve been considering buying one, I’d recommend doing so ASAP — it may never be this affordable again.

Operations tech leader Samsara has unveiled a host of new hardware and tools aimed at making fleet management more intelligent than ever, as well as boosting driver efficiency and safety.
At its Samsara Beyond 2026 event in Las Vegas, the company revealed its new 360 camera, designed specifically for heavy equipment and operations usage, making it easy to navigate around crowded sites and factories.
It also revealed an expansion to its dash cam platform which will now include two-way voice capabilities, allowing dispatchers or even AI agents to communicate easily with workers in the field.
Smarter camerasSamsara says its new device is the first 360-degree camera built for operated equipment, and looks to address one of the most annoying pain points for workers everywhere.
On crowded sites, depots or factories, navigating huge and heavy equipment or delivery trucks can often be incredibly tricky, leading to possible safety risks and dangers for workers.
However the new camera can now provide a full 360-degree view from a single mount point, including the ability to pan and zoom even in harsh weather conditions, giving insight to any risks in real-time, and allowing safety managers to track incidents in detail.
(Image credit: Samsara)Samsara also revealed new AI multicam capabilities which can provide a worker with a birds eye view, looking top-down on their immediate situation, allowing them to spot any tight situations, or avoid collisions with people or equipment, vital for vehicles like school buses, garbage trucks, yellow iron, and box trucks.
Elsewhere, new Rear Collision Warning and Vehicle in Blind Spot Detection tools will provide dynamic audio and visual alerts when a driver is reversing or changing lanes, in real time.
And to give an extra oversight to dispatchers and bosses, the company has added two-way voice communication through its dash cam, meaning AI and human co-workers can stay in contact whenever needed.
Say a driver has forgotten a vital piece of kit for a job site, or needs to detour to another depot to pick up additional hardware - the dispatcher can now call them directly, without the driver being distracted by engaging with a smartphone, or worrying about poor reception in remote areas. The system can also deliver AI alerts such as changing weather conditions, a lower speed limit, or parking restrictions at a site.
“By combining the power to see everything with the automation to act on it, we are shifting into the next gear on safety,” said Johan Land, Chief Product Officer at Samsara.
“The 360 Camera brings first-to-market visibility to operated equipment, AI Multicam gives road fleet drivers sharper awareness of what surrounds them, and two-way voice means the AI can respond the moment a question arises. Millions of frontline workers show up every day to keep our world running, and we are fully committed to helping get every one of them home safely.”

The Leica SL3-P is not a camera for everyone, and it knows it. There's no red dot logo on the front — that easy-to-spot symbol of prestige has been deliberately omitted in favor of a clean, all-black anonymity. Only the word 'LEICA' in white block capitals above the lens mount gives the game away. This is a camera built for photographers who'd rather be invisible than show off, and that philosophy runs all the way through it, with minimal controls, a stripped-back UI, and a design language that says a lot through everything it leaves out.
The SL3-P is built around the same full-frame sensor as the Panasonic Lumix S1R II. (Image credit: Future | Sam Kieldsen)Getting to grips with it takes some patience if you're arriving from a more conventional mirrorless system. With only four labelled buttons on the body, a lot of control is handed off to the touchscreen, which is polished and logically organized once you learn its rhythms. The rear LCD tilts but doesn't swivel, which is an unusual limitation for a camera at this price — and with a serious L-mount lens fitted, the combined weight is considerable. But pick it up, hold it to your eye, and look through that large, crisp EVF, and something clicks. This is a camera that feels like it was made to be used, not admired.
Image quality is exceptional — unsurprising given the 44.7MP BSI sensor, which is of the same type used by the superb Panasonic Lumix S1R II — and battery life is impressive. The autofocus is competent and handles moving subjects well enough, though it won't trouble Sony or Canon on raw speed. At around £5,150 (US pricing TBC), it's an expensive proposition. But as a pure expression of what a modern Leica should be, the SL3-P makes a very strong case for itself.
Leica SL3-P: Price and availability- Priced at $6,690 / £5,150 body-only
- Also available in three zoom lens kits
It's unlikely to come as a shock to you that the Leica SL3-P is a very expensive camera. Its launch price, for the body only, is $6,690 / £5,150 (Australia pricing is still TBC at the time of writing).
Leica is also releasing the camera in three kit bundles, each of which includes at least one Vario zoom lens. The SL3-P with a Leica 28-70mm lens is $7,790 / £6,100; with a Leica 24-70mm it's $8,390 / £6,480; and with both the 24-70mm and a 70-200mm it's $10,995 / £8,560.

Leica SL3-P: design- All-black, badge-free design with minimalist controls
- Premium full-metal construction with IP54 weather sealing
- Large, comfortable EVF with twist-barrel diopter adjustment
The absence of Leica's red dot is the first thing you notice, and it sets the tone for everything that follows. The SL3-P is clad entirely in black, with only 'LEICA' in white block capitals on the EVF housing to identify it. Four buttons across the whole body are labelled (one of which is the power button). It's a stealthy, understated thing — clearly designed for people who want to use a Leica but aren't fussed about being seen with one.
The German-made full-metal body felt exactly as solid and premium as I'd expect from the brand, and comes with IP54 weather sealing for extra outdoors reassurance. There's a large grip covered with a textured material that provides a secure hold even when conditions aren't ideal, and the supplied neck strap is thick and well-padded, which I appreciated given how much weight a serious L-mount lens adds to the equation.
Future | Sam KieldsenFuture | Sam KieldsenFuture | Sam KieldsenFuture | Sam KieldsenFuture | Sam KieldsenFuture | Sam KieldsenWith so few physical controls, much of the camera's operation is routed through the touchscreen. The UI is stylish and well organized, with photo and video modes color coded distinctly in red and yellow respectively. And while the layout takes some adjusting too if you're used to a more button-heavy system, the logic is coherent, and settings are never difficult to locate. Touch-to-focus on the screen works exactly as expected, and custom button assignments help flatten the learning curve further.
The EVF is large, crisp and comfortable thanks to its 5.76-million dot resolution and 0.76x magnification, and as a glasses wearer I really liked the satisfying diopter mechanism that simply requires twisting the EVF barrel rather than hunting for a small dial.
(Image credit: Future | Sam Kieldsen)The top-plate display is a genuinely useful feature, giving you a quick rundown of current settings without you having to lift the camera to your eye. The rear LCD, however, only tilts: up to 90 degrees upward and around 45 downward. That covers most tripod and arm's-length scenarios, but there's no forward-facing position for self-shooting, and no side-to-side articulation, which feels like an unusual limitation at this price.
On a practical note, I will say that the SL3-P is not a lightweight system, especially when teamed with some high-quality glass. The Summilux-SL 50mm f/1.4 lens I used with it added over a kilogram to the body, and while the grip is secure and comfortable, a long day of handheld shooting (covering a child's birthday party, in my case) does become fatiguing. That's less a criticism — after all, there are plenty of heavy cameras around — and more of a warning about how and when it can be used.
Leica SL3-P: Performance- Exceptional image quality from a 44.7MP BSI full-frame sensor
- Competent hybrid autofocus with broad subject detection, including birds
- Impressive battery life and extensive video options including 8K and ProRes
The SL3-P shares its 44.7MP BSI full-frame CMOS sensor with the Panasonic Lumix S1R II — a camera I've tested and rate very highly — and the image quality is, predictably, exceptional.
Raw files processed in Lightroom offer tremendous latitude, with smooth tonal gradation, wide dynamic range and excellent high-ISO performance. JPEGs are very good straight from camera too, and five film-look presets — three color, two monochrome — add some welcome creative options. The high-contrast black-and-white preset is particularly striking, and feels authentically Leica in character.
Video capabilities are more extensive than the camera's photographer-first positioning might suggest: 8K Open Gate, ProRes to 5.8K, 4K at 120fps, L-Log, 12-bit RAW and 4:2:2 10-bit are all available. It's a serious toolkit, even if the handling feels more naturally attuned to stills.
Future | Sam KieldsenFuture | Sam KieldsenFuture | Sam KieldsenFuture | Sam KieldsenFuture | Sam KieldsenFuture | Sam KieldsenThe hybrid autofocus combines 315 contrast AF points with 819 phase detection points, with human, animal (including birds) and car detection. Tracking held up well in practice; testing on an active cat, the camera maintained focus through erratic movement without significant trouble.
Outright acquisition speed with the Summilux 50mm f/1.4 in AF-C is where it falls short of class leaders; it's capable rather than decisive, and anyone shooting fast action should look elsewhere. For portrait, street or documentary work, though, it certainly gets the job done.
Five-axis IBIS rated at up to five stops works quietly and effectively, and battery life is a genuine highlight. After a full charge I shot well over 100 frames across a lengthy session, and the indicator remained full. That seems in line with Leica's claimed 383 shots per CIPA standard cycle.
Should you buy the Leica SL3-P?Buy it if...You value craft and image quality above speed
The build, finish and sensor are among the best in class. For considered, unhurried shooting, this is a very rewarding camera to use.
You want a discreet full-frame system
The badge-free design and understated profile make the SL3-P ideal for work where a conspicuous camera would be a liability.
You need fast and precise autofocus
Sony, Canon and Nikon all offer more decisive AF systems at comparable or lower prices. The SL3-P's AF is capable rather than class-leading .
Solo video is central to your work
The tilt-only screen and stills-focused handling mean this isn't the best choice for self-shooting video creators.
- Leica loaned me a sample for over a week, along with a 50mm prime lens
- I used it indoors and outdoors for several days, shooting photos and video
- All sample photos were shot in raw and processed in Adobe Lightroom
Leica loaned me a review sample of the SL3-P camera to test out in real-world use, a few weeks ahead of the official release.
I reviewed the Leica SL3-P over the course of a week, using it exclusively with the Leica Summilux-SL 50mm f/1.4 ASPH. prime lens. My shooting covered a wide range of scenarios: street photography and candids outdoors, landscape work, and indoor shooting in both natural daytime light and normal interior lighting at night — the latter without flash or studio lighting assistance of any kind.
All sample images were captured in raw format and processed in Adobe Lightroom.
First reviewed June 2026
- Amazon is hiring 11,000 new workers, mostly new graduates and interns
- Garman says they're more impressionable and willing to adopt AI
- Willingness to learn could be more important than existing skills
Amazon CEO Matt Garman has confirmed the company's plans to hire 11,000 interns and new grads this year despite an ongoing internal push for AI tools.
The news comes around six months after the company warned that 16,000 workers would be losing their jobs, with Garman's cloud business hit hard.
With the latest news, the company looks to be refocusing human resources instead of getting rid of human workers altogether as business priorities change and new opportunities open up.
Amazon to hire 11,000 workers in the same year it laid off 16,000Speaking with Casey Newton of Platformer in a YouTube interview, Garman explained that white-collar jobs are changing as a result of AI, but they're not being eliminated. He compared AI to Excel spreadsheets, which dramatically increased productivity for accounting and finance work.
"If you look at what your job was two years ago, and what your job is going to be in two years, it's going to be vastly different," he said.
Garman also noted a shift in where humans bring the most value – writing code itself is becoming less valuable, but engineers are still important reviewing AI-generated code, understanding business requirements and designing systems with the AI-generated code.
As for why the company is hiring junior workers specifically, Garman acknowledged that they're among the cheapest labor to hire, but they also learn company culture faster and can embrace AI more positively than older generations.
The CEO previously said that replacing junior employees with AI was "one of the dumbest things I've ever heard."
Without hiring graduates today, companies risk creating a long-term skills gap in the future because they have nobody to train into senior and experienced engineers, he added.
He implied that recruitment is becoming more about a willingness to learn, not the skills that have already been mastered, but the interview ultimately confirmed the continued value of human workers.
- Nothing has shown off the design of the Phone (4b)
- This includes a dual-lens camera, an LED light bar, and big bezels
- Fans aren't sold on it, but would buy the concept phone that Nothing also recently showed off
Following a recent tease, Nothing has now shown off the full design of the Phone (4b), even though the handset won’t be fully detailed until July 7.
From this, we know that the Nothing Phone (4b) has a dual-lens camera with vertically arranged lenses, in a large camera block with a textured finish. It also has an LED light bar similar to the Nothing Phone (4a)’s, while around the front there’s a punch-hole camera and a flat screen with large bezels.
It’s a design that seems fine if a little less unusual or inspired than many Nothing handsets, but it’s one that fans largely aren’t impressed by.
Phone (4b).7 July, 11:00 BST. pic.twitter.com/ksHy9hTM1xJune 25, 2026
Responses to the teaser on X include “most average Nothing design,” and “very disappointing,” while over on Reddit, comments include “looks bad” and a simple “eww.”
So unless the specs or price make up for the design it seems this might not be a big hit for Nothing, and if — as we’ve previously speculated — this was originally intended as a CMF phone, it’s unlikely it will have too much going for it in the specs department, while the Nothing branding will likely mean a higher price than it would have had as a CMF device.
The phone fans wantBut Nothing also recently showed off a handset that fans actually are excited about — sadly though this was just a concept device, which is unlikely to ever see the light of day.
The phone in question appeared in a YouTube video, where Nothing designed a handset with the dream features put forward by the brand’s community. These include a small (sub-6-inch) screen, a pop-up selfie camera, a dual-lens rear camera, a headphone port, and a microSD card slot.
The company did note that to make this a reality it would need to be quite thick, and even then probably couldn’t fit in more than a 3,800mAh silicon-carbon battery, so that’s perhaps part of why the team doesn’t seem interested in making this a real device.
But perhaps it should, as reactions to the video included “I would 100% buy this,” “beautiful,” and “forget Nothing Phone 4. Just make this.”
So it seems that — at least among Nothing’s most vocal fans — there’s real demand for this handset, and little interest in the Phone (4b).
- Nvidia’s closed-loop liquid cooling system virtually eliminates water waste
- Direct-to-chip cooling transfers heat more effectively than air
- It enables higher performance-per-watt and higher rack densities
Data centers aren’t without their fair share of criticism – energy-intensive compute raises temperatures and giant campuses consume considerable amounts of air and/or water to keep them running optimally.
Land scarcity and financial incentives have also been pushing new developments closer to high-risk areas, including drought-prone regions, ultimately leading to even higher cooling requirements.
But Nvidia knows this, and it knows traditional air cooling has pretty much reached its limits as AI hardware becomes denser and denser.
Closed-loop cooling virtually eliminates water wasteWith cooling now a core part of AI infrastructure design, Nvidia’s latest liquid-cooled AI systems promise higher thresholds to reduce the burden, driving down water and energy consumption as a result.
By running coolant at higher temperatures – 45°C or 113°F, to be specific – it enabled simpler cooling systems and lowers electricity consumption. Nvidia’s concept uses 75% water, 25% glycol as a coolant, noting that it can run about 5-7°C higher than hot tubs.
Compared with traditional evaporative cooling towers, Nvidia’s latest proposition involves a closed-loop system where coolant continuously circulates through servers to remove excess heat from chips. The warm coolant then cycles through external dry coolers leaving virtually no water evaporation.
The company boasted that cooling-related water consumption can be reduced by as much as 100% in suitable climates subject to the occasional extreme day, with cooling towers totally eliminated.
“The Nvidia DSX reference design for AI factories has zero water consumption – we have eliminated massive amounts of power usage and pretty much all water usage,” Data Center Cooling and Infrastructure Director Ali Heydari said.
The system’s efficiency primarily comes from direct-to-chip liquid cooling, where liquid flows directly through cold plates attached to CPUs and GPUs. This captures and expels the heat from exactly where it’s produced.
Not only is this more effective than cooling entire rooms, but liquid also promises to transfer heat thousands of times more effectively than air.
Major improvements across water consumption, energy efficiency and Power Usage Effectiveness (PUE) all help on the sustainability front, but there’s another layer to the benefits.
Nvidia says it can increase rack density and performanceNvidia acknowledged that chip power consumption and rack densities continue to rise, so by implementing liquid cooling data center companies can add more GPUs per rack, use higher rack power and ultimately pack in larger AI clusters within the same building footprint.
The company explained that its Rubin systems now fit inside two racks, instead of six, marking a major space saving.
Simultaneously, air cooling has become ineffective. “Once the watts per chip crossed a certain level, liquid cooling became mandatory,” Motivair’s CEO Richard Whitmore said.
Independent testing totally separate from Nvidia’s latest announcement shows that its H100 systems delivered around 17% higher performance when water cooled, compared with air cooling. Under sustained AI workloads, GPU temperatures fluctuated between 41-50°C when water cooled, and 54-72°C when air cooled.
Besides improving immediate and sustained performance, greater thermal efficiency could also boost longevity.
The new, higher-temperature closed-loop water cooling model is set to be used in upcoming Rubin deployments this year.
