Virus found hiding in gut bacteria linked to colorectal cancer

Gizmag news -

Colorectal cancer (CRC) has long been linked to a microbial imbalance in the gut, a phenomenon scientists call dysbiosis. But a new study from the University of Southern Denmark and Odense University Hospital points to this dynamic being more complicated than initially thought, with not just bacteria behind it but the viruses living inside them.

Cotton-like fluffy fabric stores and releases heat while repelling moisture

Gizmag news -

Cotton may be nice and soft and warm, but we're told not to wear it for sporting activities because it traps moisture, becoming wet and ultimately drawing heat away from the body. Well, scientists have created a synthetic fabric that is claimed to repel moisture while still replicating the coziness of cotton.

First consumer wing-in-ground effect aircraft takes flight

Gizmag news -

Navee – a Chinese mobility brand that's probably best known for e-scooters like the ST3 Pro and UT5 Ultra X and electric dirt bikes such as the Storm X Pro, but also has golf carts and exoskeletons in its ecosystem – just adapted one of the Cold War's strangest engineering ideas into a personal watercraft that is part aircraft, part boat. The Suzhou-based company unveiled its WaveFly 5X at Lake Taihu on June 5, calling it the world's first wing-in-ground effect (WIG) vehicle for everyday consumers.

Our 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, full even light and low directional light, to see the effect of different lighting conditions.

Shooting in Raw at its base ISO, the L10 captures a good amount of detail, on par with the Sony and Canon, and slightly more than the LX100 II. Despite using the same amount of sensor area as the LX100 II, it provides an image that's 1EV cleaner thanks to its ability to gather more light by shooting at ISO 100 instead of 200. Likewise, it produces slightly less noise than its Type-1 peers, thanks to its 66% increase in sensor area.

This advantage continues through to higher ISOs, though if you find yourself shooting in the dark often, it's worth considering the noise advantage that APS-C compacts like the Ricoh GR IV or Fujifilm X100VI provide, at the cost of less versatility thanks to their prime lenses. The L10's JPEG engine does a decent job of retaining details while reducing noise, though the older cameras that act as its competition are decent in this regard, too.

Standard Color Profile L.Classic Neo L.Classic L.Classic Gold The L10 has pleasing colors in its standard color mode, and a variety of other profiles, with the option to experiment further, through the use of uploadable LUT files.

Where Panasonic's processing has improved is when it comes to its JPEG colors. Overall, they're pleasing and more punchy, and we've enjoyed them in the pictures we've taken with it outside of the studio. And if you don't enjoy the colors in its built-in modes, it's almost infinitely customizable thanks to the L10's Real Time LUT system.

Dynamic Range

The L10 provides plenty of latitude to shoot to preserve highlights, then brighten in post.

The sensor used in the L10 has been shown to have great dynamic range in the other cameras we've tested that use it, and we're happy to say the L10 is no exception. While its deepest shadows aren't quite as clean as those of the cameras that use the sensor's entire area, you still have plenty of room to exploit them. There's perhaps not as much difference as we might expect from a camera that can combine high and low gain readout in a 16-bit space, vs the 12-bit, single-read approach from the LX100 II, but they should still be pretty flexible.

Likewise, the sensor has very little read noise, giving you the option to choose an exposure, then lower your ISO to preserve highlights without having to worry about a ton of additional noise showing up in post when you raise the shadows. Shots at ISO 100 pushed 4EV will show a little more noise than shooting at ISO 1600 in the first place, but even by ISO 200 the difference isn't particularly distinguishable.

Lens performance Image ComparisonThis widget is not optimized for RSS feed readers. Click here to open it in a new browser window / tab.

When we reviewed the LX100 II in 2018, we said that camera's 17MP sensor was showing the limits of the lens. With the L10 essentially using the same optics, paired with a higher-resolution sensor, that's even more true today, with noticeable softness in the corners even when stopped down to F4 or 5.6 (though doing so provides noticeable improvement versus faster apertures like F2.8).

The bright, complex, foldable lenses on compacts are quite susceptible to sample variation, and we aren't able to test multiple copies of the camera. Putting it in the studio scene also pits it against extremely high-quality primes, many of which are larger and heavier than the L10 in its entirety, and holds it to a higher standard than most would expect from their real-world shooting. In the process of shooting our sample gallery, we haven't come across many situations where the lens felt inadequate for what we were trying to capture.

L-mount finally gets a truly tiny lens

Digital Photography Review news -

The Viltrox AF 28mm F4.5 "Chip" is finally available for L-mount.

Image: Viltrox

After months of teasing, Viltrox has released the L-mount version of its full-frame AF 28mm F4.5 "Chip" lens. It becomes the company's second autofocusing lens for the system since it joined the alliance in September, 2025, and is a truly tiny option for people with cameras that use the mount.

The lens design has been around for a few years on Sony E and Fujifilm X mounts, and it gets its name and notoriety from its size: it's 15.3mm (0.6") thick, and weighs 60g. That, and its relatively wide focal length, make it an attractive prospect for anyone looking for an as-small-as-possible kit for everyday shooting.

That's an especially interesting proposition on L-mount, where there haven't been that many choices for that kind of lens, despite how much small, gripless cameras like the Panasonic S9 and Sigma BF would benefit from one. Panasonic itself released a relatively small 40mm F2 recently, and there are a few similarly-sized options from other brands, but even those are still noticeably bigger and heavier than the Chip. And while Panasonic's 26mm F8 is similarly-sized, it's quite a bit slower, and manual-focus only.

Image: Viltrox

Conversely, the Viltrox has a voice coil motor (or VCM) for autofocus and can't be manually focused. It also includes an integrated lens cap, which you can deploy by sliding a switch to keep the front element protected if you're sliding the lens into a bag.

The lens is made up of six elements in six groups, with two aspherical and two ED lenses, as well as coatings to reduce reflections and to repel water and oils from the front element. Perhaps its biggest is the aperture: while you may be willing to trade the speed of the ~F2 options for the size and weight savings, it is worth noting that the Chip is a fixed F4.5 lens, meaning you also can't stop it down any further if its particularly bright or if you want to capture more depth of field or blur motion.

While it's exciting to see Viltrox release a new lens for L-mount, especially one that fits into an underserved niche, this release also highlights the company's relatively slow entrance into the L-mount ecosystem. In the ten months since it announced it was joining the alliance, it's only released this lens and its 16mm F1.8 for the mount, both of which were promised at the beginning. In that time, it's released six other full-frame lenses for other mounts (mainly Sony's E and Nikon's Z), with the only word on L-mount versions coming in the form of responses to Instagram comments.

Still, the release of the AF 28mm F4.5 Chip is a sign that there's at least some work being done at Viltrox for L-mount. It's available today for $99.

Press release:

Viltrox Launches AF 28mm F4.5 Chip L-mount Lens

Shenzhen, China, June 16, 2026 — Viltrox today announced its new AF 28mm F4.5 Chip L, a full-frame autofocus pancake lens for L-Mount cameras. The lens combines an ultra-slim profile, exceptional lightness, and excellent portability that’s ideal for everyday shooting, travel, and street photography.

With the launch of the AF 28mm F4.5 Chip L, Viltrox further expands its L-Mount lineup. In addition to support for in-camera correction functions, the lens is optimized to work seamlessly with modern L-Mount camera systems, delivering a compact and effortless shooting experience for everyday photography.

Weighing just ~60g and measuring just 13.2mm thin, this ultra-compact autofocus lens is comparable in size to a simple lens cap or camera body cap, transforming a professional mirrorless camera into a pocket-friendly companion. When paired with cameras such as the Panasonic Lumix S9 and Lumix S5II, the AF 28mm F4.5 Chip L creates a remarkably compact full-frame setup, allowing photographers to stay highly mobile with minimal bulk.

An Ultra-Lightweight Pancake Lens for Everyday Creativity

The Viltrox AF 28mm F4.5 Chip L features a fixed F4.5 aperture and a VCM (Voice Coil Motor) autofocus system that delivers fast and quiet autofocus performance. Its versatile 28mm focal length and minimum focusing distance of just 0.32m make it well suited to a wide range of everyday shooting scenarios, providing a natural balance between environmental context and subject emphasis.

To maximize convenience, the lens incorporates a signature slide-lever lens cover design. This built-in mechanism allows users to open and close the integrated lens cover without the need for a separate lens cap, further streamlining the transition from carrying to capturing.

The lens also features a distinctive polygonal aperture plate design that produces recognizable starburst effects around point light sources in backlit and night scenes, adding a unique visual signature to select images.
