Panasonic is tallying up the “world’s firsts” in a slew of announcements made Friday, May 31. In addition to revealing the first full-frame 6K camera in the Lumix S1H, it also announced a new lens for its smaller Micro Four Thirds system, the Leica DG Vario-Summilux 10-25mm f/1.7. The zoom lens is designed with both still photographers and video shooters in mind, and is the first standard zoom to feature a constant f/1.7 aperture.
Impressive as it is, such a combination of wide aperture and zoom range is certainly easier to achieve on the Micro Four Thirds format compared to lenses for larger full-frame sensors. The 2.5x zoom offers a 20-50mm full-frame equivalent focal length, while the f/1.7 aperture is equivalent to f/3.4 on full-frame. Still, it is by far the fastest zoom lens to grace the Micro Four Thirds format thus far, while also offering a unique focal range not quite matched by other zooms.
Composed of 17 elements in 12 groups, including three aspherical elements and four extra-low dispersion (ED) elements, the 10-25mm f/1.7 promises image quality worthy of its Leica nameplate (as part of its partnership with Panasonic, Leica lends its name to certain Panasonic lenses that meet stringent quality standards). It also features a 9-blade aperture which should provide more circular out-of-focus highlights.
Beyond optical quality, the new zoom is sealed against dust and moisture for use in all weather conditions. Targeting Lumix GH5 and GH5S owners, it also incorporates a special mechanism to suppress focus breathing — where a lens appears to zoom slightly when adjusting the focus — which is important to videographers.
In addition to the Micro Four Thirds lens, Panasonic also introduced two teleconverters for its full-frame S series cameras. The DMW-STC14 and DMW-STC20 provide magnifications of 1.4x and 2x, respectively, and are compatible with the existing 70-200mm f/4 and upcoming 70-200mm f/2.8 lenses.
Prices for the new teleconverters haven’t been announced, but the 10-25mm f/1.7 lens will go for $1,700 when it releases in July — certainly not cheap, but we might have expected worse. Panasonic’s older 12-35mm f/2.8 has an MSRP of about $1,000, and while the 10-25mm doesn’t have as much range, the aperture is over twice as wide.
Full-frame cameras tend to be chunky beasts, but Sigma wants to prove that big imaging doesn't need a big body. Enter the Sigma FP2, the successor to its tiny, boxy fp mirrorless camera. It keeps the same modular design but packs in some serious upgrades, including a 24.5-megapixel partially stacked full-frame sensor, improved autofocus, 6K video recording, and 70GB of built-in storage. Sigma calls it the world's smallest full-frame camera, and while it might be tiny, the same cannot be said for its price tag.

A phone thermal camera is one of those tools you don’t think you need until the first time it saves you from an expensive problem, and the Thermal Master P3 just got easier to try. For Halloween, it’s discounted with the code THERMCAM10, a 10% cut that works out to $107 off the total. It’s also fresh off a win at the 2026 Tom’s Guide AI Awards for best phone thermal camera, which is the kind of third-party nod that separates a serious tool from the cheap clip-on sensors that flood this category.
We are nearing Amazon's Prime Big Deal Days, which officially run October 6 and 7. But there is no need to wait until the sale begins to start looking. Early offers are already live, and camera gear is one category where I found enough worthwhile discounts to put together a proper creator-focused list.
I’ve deliberately gone wider than interchangeable-lens cameras here. There are pocket and action cameras, a 360 camera, an instant camera, two wireless microphone systems, and a pair of webcams covering very different budgets. Prices were checked on October 2, and as always with Amazon, they can move quickly.
