SIGMA fp2: 6K open gate in a 376 g full-frame body, and who it is for

SIGMA 28-70mm f/2.8 DG DN Contemporary L-Mount lens

Impulse Cameras |

SIGMA has announced the fp2, the follow-up to the pocket-sized full-frame body that filmmakers have been rigging up since 2019. We are an authorized SIGMA dealer, so people have already been asking us what it is and who it suits. Here is our read, with the numbers taken from SIGMA's own product page.

What it is

The fp2 keeps the idea of the original fp: a small L-Mount full-frame body built to be a camera you add parts to. The sensor is new. It is a 24.5 megapixel partially stacked full-frame CMOS, and SIGMA lists up to 20 frames per second for stills. The body adds a tilting screen and dust and splash resistance.

  • Price: $2,199 for the body, as listed on SIGMA's US site

What changed from the original fp

The original fp recorded 4K, and its RAW video went out to an external recorder. The fp2 aims higher: 6K open gate and ProRes RAW are headline features, and the internal storage gives you a place to record without leaning on a card. Open gate means the camera records the whole sensor area, so you can crop to vertical, widescreen or square later from one take.

Who it is for

Filmmakers who like small rigs. If your camera lives on a cage, a gimbal or a drone, a 376 g body is the point. Less weight on the gimbal means easier balancing and longer days.

Hybrid shooters. Twenty frames per second and a stacked sensor make it more than a video box, though it is still a camera built around a modular body.

Anyone already in L-Mount. The mount is shared across several brands, so the lens choices run deep. If you want a feel for the glass, these are ones we carry:

Honest trade-offs

A body this small makes compromises, and you should know them before you order. The 130 minutes of continuous recording SIGMA quotes means spare batteries or external power on long shoots. Electronic stabilization is not available in 6K, according to CineD's report, so a gimbal or a stabilized lens matters more. And the fp2 is a build-it-yourself camera: cage, grip, monitor and audio will likely be on your list, and their cost belongs next to the $2,199 body price.

Two details we could not pin down. SIGMA's page gives two different figures for internal storage, so check before you plan around it. And SIGMA's page does not state a ship date. CineD reports November 11, 2026, which we are treating as a report until SIGMA or our rep confirms it.

Come try L-Mount glass, or ask us

We do not have an fp2 listed yet, so we cannot take an order online today. Stop by Drexel Town Square in Oak Creek and we will talk through your build, put SIGMA L-Mount lenses in your hands and share what we know about timing. Our rental program is also a good way to try a rig before you commit to one. Message us or call the shop with questions about the fp2.
