Sigma launches the world’s smallest full-frame mirrorless camera… again

Seven years after the original fp, Sigma’s FP2 keeps the small full-frame formula intact while overhauling almost everything in it for sharper stills and much more serious video.

Compact full-frame cameras have become a pretty crowded corner of the market, with models like Panasonic’s Lumix S9 and Sony’s A7C II trying to make large sensors seem like less of a compromise. Sigma was early: we covered the original fp back in 2019, when it was announced as the smallest and lightest full-frame mirrorless camera out there. The company followed up with the 61-MP fp L in 2021, then took an even more minimalist turn last year with the aluminum unibody BF.

The FP2 is the true successor to that first fp, and Sigma once again claims the title of the world’s smallest full frame body. The brick look and modular philosophy are still here, but the internals have been rebuilt around a newer, faster sensor, with a much stronger push into cinema territory.

Instead of reinventing the concept, Sigma seems to be focusing on fixing the quirks that made the original a tough sell for many shooters.

At the heart of the FP2 is a 24.5MP partially stacked full-frame CMOS sensor, likely the same chip found in the Nikon Z6III and Lumix S1II. Its faster readout is very important here because, like its predecessors, the FP2 relies solely on an electronic shutter. That means much less shutter swing, along with bursts of up to 20 frames per second (fps) for up to 200 frames. Autofocus has also been updated and subject detection now recognizes birds as well as people and animals.

The video is where FP2 is really shown. A dedicated switch on top switches between Photo and Cinema modes, each with its own interface. The camera internally records open gate 6K, including ProRes RAW at approximately 30 fps, and offers L-Log, 4K at up to 120 fps in crop mode and up to 14.1 stops of dynamic range. Add the optional hot shoe unit and Panasonic XLR adapter and you’ll even capture floating 32-bit audio.

Handy upgrades include a screen that tilts 90 degrees up and down 45.70GB of internal storage along with a UHS-II SD slot and about 30% longer battery life than the original fp. However, there is still no internal stabilization, only electronic stabilization for video. The body measures 112.8 x 69.9 x 41.8 mm (4.4 x 2.8 x 1.6 in) and weighs 446 g (15.7 oz) with its battery.

The Sigma FP2 will go on sale on November 11 for $2,199 body only. You can also pick it up for $2,749 along with the contemporary 50mm F2 DG lens or the new EVF-21, a 5.76 million-dot tilting OLED viewfinder that plugs into one of the camera’s two USB-C ports. Other new add-ons include a hot shoe unit, a baseplate with a 3/8-inch mount for video rigs, and an LCD magnifier.

That body-only price is below the fp L’s launch price of $2,499 and in the same ballpark as more conventional 24MP hybrids. The trade-offs are still very Sigma though: no mechanical shutter, no IBIS, and a gripless brick that arguably feels more at home once integrated into a platform. Early hands-on reviews generally agree that the FP2 leans toward filmmakers, although Sigma presents it as an even split between stills and video.

Still, FP2 looks like the most complete version of the FP idea yet. If you want a genuinely pocketable full-frame camera that can be expanded into a proper cinema setup when the job requires it, there’s still very little that comes close.
