We're going to be on the Moon a lot more often soon, and that means we'll need places to rest, conduct research, and work there. Building habitats and maintaining them will be tough, but bacteria could come to the rescue by helping repair cracked bricks made from lunar soil.
If you've ever eaten a pomegranate, you'll know that a great deal of the fruit is composed of its thick skin – which simply gets thrown away. Soon, however, that skin could be used in an edible coating which will help keep strawberries from spoiling.

If there's one thing you want to do immediately after completing the kind of long, exhausting hike that's mandatory when backpacking, it's rip off those shoes and let your fiery, achy feet breathe a little. But as much as you'd like to whip out your most comfortably broken-in set of slippers or sandals, it can be tough to justify the pack space and weight for such a luxury. Ultralight gear specialist Zpacks has a solution that sizes and weighs only slightly more than fresh air. Its flat-collapsing, rollable Ultralight Camp Shoes weigh less than 1 ounce per shoe and provide a comfortable, breathable refuge for tired, aching feet.

Deep sea mining has been off limits thus far, both because it's awfully hard, and because governments haven't yet firmed up regulations around extracting minerals offshore. That might soon change, as an ambitious company is moving steadily to secure permission to begin operations with the Trump administration's blessing – perhaps sooner than it should.

Happy weekend, everyone. We're deep into camera news season, but the accessory makers haven't been slacking at all. Today, we'll be taking a look at a big update to a solid audio recorder, a new take on the light stand and a host of other accessories – but first, the deals.
Canon deals Photo: Dale BaskinCanon's mid-range full-frame camera, the EOS R6 II, is currently on sale for $200 off. When we tested it, we were very impressed with how well-rounded it is, combining excellent autofocus, great ergonomics and solid performance.

It takes everything that's good about the EOS R6II and turns it up to 11, with a higher-resolution sensor, faster burst rates and more.

On the surface, its new product, the Luna, looks like a standard piece of grip equipment, but if you look closer, you'll notice it's made of carbon fiber. The company says this makes it light, stable and compact when folded up. It has a maximum height of 2m (79").
That's not its only trick, though: you can also detach the center column from the legs and use it as a boom pole for recording audio or getting your camera closer to a hard-to-reach subject. While the head features a 3/8"-16 thread, common for lighting and microphones, it's actually retractable: push down the outer sheath, and it'll reveal a 1/4"-20 thread, which can be used to mount a wide variety of accessories.
$149 at 3 Legged Thing Even more grip The Impact 3-stage Baby Folder Roller is just one of the products in the new KeyGrip series.If you prefer more traditional light stands, Impact has you covered. The company has announced a new KeyGrip lineup, which it says is supposed to provide rugged, flexible designs at a relatively affordable price. The lineup includes everything from small, sturdy stands meant to hold camera sliders to three-stage stands on rollers that can extend up to 3.35m (11') tall.
Buy at B&H Video Performance Guaranteed Image: NextorageIf you're a videographer who shoots on Sony cameras and have to be absolutely sure your storage media is fast enough for any resolution, codec or framerate, you have a new option. Nextorage has announced its NX-A2Pro series of CFexpress Type A cards, which it says are the first of their kind to comply with the Video Performance Guarantee (VPG) 800 standard. That means the cards can write at least 800MBps of data continuously.
Of course, the cards' peak write speeds are much higher, at 1900 MBps. Both speeds, however, are well above what you'll need today. The manual for Sony's flagship a1 II says that even the camera's highest-bitrate modes only require a VPG200 or higher card. Nextorage says the NX-A2Pro is designed for "the high-end camera market in the future."
If you're not looking for future-proof storage, the company also announced its NX-A2AE line, which has a VPG400 rating. Both cards will be available starting in "late April."

Buy at B&H A new school way to shoot old-school Image: CutasundaWhile shooting film gives you a completely analog experience, if you're doing so in 2025, you'll probably want to digitize your photos at some point. The Myriad film holder by Cutasunda, which got a shout-out from PetaPixel this week, promises to help make that process a little easier. It has a diffusion panel to help ensure your film is evenly backlit, and its top panel makes sure your film is flat, even if months in a canister have given it a tendency to curl up. Its adjustable film guides support film sizes from 110 to 6x9, so it'll work with pretty much whatever you're shooting.
It's not a complete package – you'll still need a quality backlight to put behind it, a camera with a macro lens and a tripod – but it plays an important part in bringing your film from the analog world into the digital one.
Buy at Cutasunda A legend improved Photo: ZoomZoom's Handy Recorders – especially the H4 and H5 lines – have been popular among videographers for years, as they provide a versatile way to capture audio wherever you are. Now, the H5 has gotten an upgrade: the new H5studio includes an even better stereo microphone capsule, as well as the ability to record in 32-bit float audio, which essentially means you don't have to worry about your audio clipping.
Like the standard H5, the H5studio has a "capsule" system that lets you attach various microphones and inputs to it. It comes standard with a stereo XY capsule that features "the largest mics ever" included in the Handy Recorder lineup, which can capture around 130dB of dynamic range. The recorder's body also features two combination XLR / TRS inputs, line and headphone out jacks, and USB-C. If you swap the capsule, though, you can add two more XLR inputs or even a dual-channel wireless receiver or shotgun microphone. The H5studio can record up to six tracks, which you can monitor via its LCD screen.

The free 11.1 update includes a few minor improvements and integrates one of the company's new AI features, but the biggest addition is Adjustment Clips. If you've ever edited in Premiere Pro or Davinci Resolve, you'll likely be familiar with the concept: it's a layer you can put over multiple other clips to apply the same effect or transition to them. This can be especially useful with color grading; if you have clips that all need the same grade applied, you can simply apply it to an adjustment clip layered over them rather than having to apply them to each clip individually.
As big as that is, it pales in comparison to what BlackMagic has been working on. The company announced a new version of its Resolve editing software that adds an AI tool for creating animated subtitles, a dedicated keyframe editor and an even easier-to-access audio mixer.
Photo: BlackMagicIts blockbuster announcement, though, is the Blackmagic Camera 9.5 Update, which is currently in beta but provides a massive upgrade to the autofocus system for the Blackmagic Cinema Camera 6K. When it launched, the camera just had single autofocus – the camera could focus once but wouldn't update if your subject moved. The new update, though, adds continuous autofocus, which will work to keep whatever's under its selected focus point sharp. It also supports tracking autofocus, where it will attempt to keep its focus point on a selected subject, even if it moves or the framing changes, as well as face tracking autofocus. These changes should make the camera substantially more useful for smaller productions or even single-shooter setups with no dedicated focus puller. The company says it'll be bringing the feature to its other large-sensor cameras as well.
A new lens company hailing from China has popped onto the scene, promising even more autofocus lens options for mirrorless cameras. Named SongRaw, the company's slogan states, "Crafted with Dedication, Honoring Your Passion and Love," adding that it "is dedicated to polishing every detail of the craft." To kick things off, it has announced a fast 50mm lens that it claims is the first Chinese 50mm F1.2 full-frame autofocus mirrorless lens.
SongRaw's debut lens is a full-frame offering that provides that classic 50mm focal length with a wide aperture for a shallow depth of field and better low-light performance. The lens features 13 aperture blades, which SongRaw says promises "beautiful bokeh." It offers autofocus powered by a stepping motor, which SongRaw says is compatible with eye-tracking. It can focus as close as 0.52m (20.5") and is compatible with 72mm filters.
The optical design comprises 15 elements in 10 groups. The information on special elements is a bit mixed, with one piece mentioning two aspherical elements and another including two extra-low dispersion elements. It wouldn't be out of the question to see both in the same lens, though. SongRaw didn't provide any details as to the size or weight of the lens.
Image: SongRawThe lens is marked with "Moonlit," and the company's barebones website includes that branding. Photos of the lens show an aperture ring, along with a switch labeled "click," suggesting the aperture ring can be clicked or de-clicked. There's also an AF/MF switch and what could be a function button.
SongRaw says the 50mm prime lens will be compatible with FE-mount, Z-mount and L-mount, but that it is prioritizing the Sony model. Nikon and L-mount users may need to wait a bit longer. SongRaw is showing the lens off at NAB, so anyone headed to the show could check it out in person. The lens will be priced at around $1000 and should be available by the middle or end of April.
