You know those adorable mini-multitools you've seen dozens of lately? The ones that are brilliantly packaged into the tiniest possible forms but likely not all that useful for doing actual work? Well, the Adventure Mate V3 isn't one of them. In fact, it's the opposite. This unapologetically big, bruising instrument won't fit in your pocket or even a loaded backpack, but it will get actual work done when you need it to. Whereas the tiny blades on a traditional multitool might whittle a tree branch, the V3 will take down the whole tree, split it into firewood and dig the bonfire pit.

Happy Friday, folks. This week, Canon has reintroduced new firmware for the EOS R1 and R5 II. It brings new features and bug fixes to both models. Additionally, Fujifilm has announced new firmware for seven cameras that offer minor updates and fixes. Without further ado, let's dive in.
Canon Image: CanonCanon initially released firmware for the R1 and R5 II last week. Those updates came at the same time as new firmware for a list of other models, but Canon had to pull the R1 and R5 II upgrades after discovering an error. It's fixed that error, and the firmware is again ready for download. If you downloaded and installed the pulled version, make sure to update to the one released on July 24 (version numbers below) to avoid any potential issues.
Canon EOS R5 II Ver 1.1.1There are quite a few updates for the R5 II. It adds automatic flicker detection at 100 or 120Hz when using Live View and improves image stabilization control with lenses compatible with Peripheral Coordinated Control. Sports photographers will benefit from the option to expand Servo AF to better focus on subjects behind nets, and it promises improved AF tracking during video with difficult-to-focus subjects.
You can also now set the number of shots captured in pre-continuous shooting mode. And, it adds the ability to turn on Exposure Simulation when using a flash unit.
Additionally, Ver 1.1.1 adds compatibility with CFexpress cards up to 8TB. Canon does note that cards larger than 2TB cannot be used for updating firmware, though. Plus, like the other recent Canon firmware updates, it enables firmware updates when the camera is connected to the internet.
If you previously downloaded Ver 1.1.0, this update fixes the two potential issues associated with that version.
See all changes and download the R5 II firmware Ver 1.1.1 here.
Canon EOS R1 Ver 1.1.2 Image: CanonThe EOS R1 shares most of the same updates as the R5 II. That includes automatic flicker detection at 100 or 120Hz when using Live View, internet-based firmware updates, the option to expand Servo AF to improve focus on subjects behind nets and improved AF tracking during video capture with difficult-to-focus subjects. It also adds compatibility with 8TB CFexpress cards and Exposure Simulation with flash units.
The R1 gets the added benefit of Panning Assist, which applies image stabilization and subject blur correction during exposure when panning with compatible lenses.
See all changes and download the R1 firmware Ver 1.1.2 here.
Fujifilm Image: FujifilmFujifilm released minor firmware updates for the X-T5, X-Z20, X-T50, X-M5, X100VI, GFX100RF and X half. All seven of those cameras now have enhanced security for wireless communication and some small updates to menu options. The X half firmware fixes a rare bug that caused the camera to freeze when the power is turned off and on.

Viltrox Image: Viltrox Viltrox AF 28mm F4.5 FE lens Ver 1.07Finally, Viltrox released an update for the E-mount version of its 28mm F4.5 lens. It's a small change with limited detail, simply saying it "fixed known issues."
While it's estimated that millions worldwide suffer from chronic fatigue syndrome, a test for the condition still doesn't exist. That could be set to change with the release of a new study that finds the condition's fingerprint in the gut microbiome.

After Sony's surprise announcement of the RX1R III, the latest iteration of its full-frame photographers' compact, we had a lot of questions that we knew could only be answered by getting hands-on time with it. Now that we've tested it in our studio and spent time shooting with it in a variety of situations, we have answers.
We're still at work on our in-depth written review, but we've covered the essentials of its image quality, autofocus performance and, of course, price, in our video review, which you can watch now.
Be sure to stay tuned for our full sample gallery and more analysis, and check out the DSC-RX1R III in our studio scene to see how its sensor and lens perform.
Gut support cells communicate with surprising precision – like brain neurons – using tiny extensions to send instructions to the stem cells responsible for maintaining and healing the intestine. The discovery may change our understanding of tissue repair and gut diseases.

Why do wrinkles form as we age? A new study has revealed that aging skin stretches more sideways under tension, causing it to buckle – like Silly Putty – into deeper, straighter wrinkles. And it all starts with how collagen is arranged.

As usual, one of the first things we did when we received the Sony DSC-RX1R III was take it into our studio, to see how it performs.
The camera's lens has a degree of distortion but correcting it isn't compulsory, so we've matched the way we shot the RX1R II: JPEGs with distorion correction applied, Raw files without. However, it's worth noting that Adobe Camera Raw applies chromatic aberation correction automatically.
Studio sceneOur test scene is designed to simulate a variety of textures, colors and detail types you'll encounter in the real world. It also has two illumination modes to see the effect of different lighting conditions.
Image ComparisonThis widget is not optimized for RSS feed readers. Click here to open it in a new browser window / tab.We'll take a closer look at the lens in a separate test, but you can see the RX1R III's sensor performs as you'd expect. It can't quite match the Leica Q3 43 for detail but it's capturing finer detail than the Mark II, with its 42MP sensor, could. Noise is comparable with the two other cameras with which it shares a sensor and with its predecessor, when compared at a common output size.
The JPEG engine does a good job of pulling out fine detail, and retains it to a reasonable degree at high ISO. Color rendition seems to be a match for recent Sony cameras, with perhaps slightly less bluey greens and greenish yellows than the RX1R II had.
A closer look at the lensOur test scene isn't designed for testing lenses but allows a reasonable working distance, so the results shouldn't be too far removed from those you get from everyday shooting (we'll be publishing a sample gallery in the coming days, to let you compare). It also lets you examine when the lens sharpens up and when vignetting disappears.
The images in this scene have been processed with geometric distortion correction on and off. They have also been processed with a slightly higher level of sharpening than the one we use for out standard test scene, to give a better idea of what you can get out of them.
Image ComparisonThis widget is not optimized for RSS feed readers. Click here to open it in a new browser window / tab.The first thing you see is that the vignetting present at F2.0 has all but gone by F2.8. Whereas sharpness takes longer, still improving when you get to F5.6.
Turning the corrections off reveals a degree of barrel distortion but it's only something you're likely to notice if you're shooting test charts or brick walls. There doesn't seem to be any significant loss of sharpness if you correct the results, so it's really a question of taste whether you choose to apply the corrections.
Overall it's fair to say the high pixel count starts to reveal the limitations of the lens at wider apertures, but still does a good job when stopped down. And, although the two aren't perfectly comparable (the Leica was processed with Capture One, which doesn't support the Sony yet), the performance is well short of the Leica Q3 43's lens at wider apertures.
In practice we found that, while it lacks critical sharpness at the distances and apertures used for portraits, it delivers all you might expect for landscape shots.
Glass isn't as easy to recycle as we might think, so we need as many ways to turn it into new products as we can devise. Researchers at the University of Portsmouth have developed a way to use powdered discarded glass in building blocks for construction, which could make this versatile material a lot more sustainable.
