Sigma fp Mirrorless Camera Body, Black {24.6MP}

Sigma fp: world's smallest full-frame mirrorless, built for cinema

The fp is what happens when Sigma strips a full-frame camera down to its essential geometry. At 112.6mm wide and 422g with battery, it fits in a jacket pocket while housing a 24.6MP BSI CMOS sensor behind a L-mount, the same mount shared across Sigma, Panasonic, and Leica glass. The body is die-cast aluminum alloy front and back, weather-sealed at 42 points, with a dedicated heat sink between the sensor and the 3.1" touchscreen. There is no mechanical shutter here, no mirror box, nothing that isn't load-bearing.

For filmmakers, the fp makes a strong case on paper and in practice. Internal CinemaDNG recording at 8, 10, or 12-bit up to UHD 4K is built in, and the HDMI output pushes 12-bit RAW up to DCI 4K at 24fps to an external recorder, giving cinematographers a genuine raw pipeline from a body smaller than most speedlights. Sigma cites 12.5 stops of dynamic range in 12-bit CinemaDNG mode. The camera also includes shutter angle display, zebra patterns, waveform monitor, timecode, and a director's viewfinder function that simulates framings from other cinema systems. For stills, 18 fps burst shooting is available, though the 12-frame RAW buffer caps its usefulness for sustained action.

The fp suits documentary shooters, travel photographers, and hybrid video operators who want a full-frame sensor in a rig that can scale, attach a grip, bolt on the optional EVF-11, connect a SSD via USB-C, and you have a modular cinema tool. Leave those off and you have a coat-pocket full-frame that shoots 14-bit RAW stills to an UHS-II SD card. Either way, you're paying for a sensor and a mount in the smallest possible chassis that can honestly claim both.

FAQ

How small is the Sigma fp compared to other full-frame mirrorless cameras?

At 112.6mm wide and 422g with battery, it's the smallest and lightest full-frame mirrorless on the market. You can fit it in a jacket pocket without an optional grip or external viewfinder.

What's the video pipeline for external raw recording?

The fp outputs 12-bit raw via HDMI to DCI 4K at 24fps, or 12-bit 4:2:2 to UHD 4K at up to 29.97fps. You record directly to an external SSD via USB-C, making it a genuine raw cinema workflow in a pocketable body.

Why does the fp use electronic shutter instead of a mechanical one?

Electronic shutter lets Sigma eliminate the mirror box and maintain the compact form factor. There's no mechanical complexity taking up space, and you get silent operation every time.

What autofocus system does the fp use?

The fp uses contrast-detect autofocus only, not phase-detect. It works but isn't fast. For stills, AF-S (single-shot) is reliable; for video, contrast-detect is adequate for static scenes but struggles with tracking.

Can I use Sigma or Leica glass on the fp?

Yes. The L-mount lets you use 14 native Sigma L-mount lenses, Leica glass, and Panasonic L-mount lenses directly. You can also adapt 29 Canon EF and Sigma SA DSLR lenses plus 13 Sigma CINE lenses via the MC-21 converter.

What's the buffer depth when shooting burst?

At 18 fps, you get 12 raw frames before the buffer fills. For sustained action shooting, this is a hard limit-not a camera for sports or wildlife.

Does the fp have internal raw recording?

Yes. It records 8, 10, or 12-bit CinemaDNG internally to UHD 4K at 24fps, with rated 12.5 stops of dynamic range in 12-bit mode. Stills are 14-bit raw to UHS-II SD card.
