Check Shot Count →The Sigma fp (2019) holds the distinction of being the world's smallest and lightest full-frame mirrorless camera. Built around a 24.6 MP BSI CMOS full-frame sensor in the L-mount system, its ultra-compact body (112.6 × 69.9 × 45.3 mm) was made possible by a key design decision: no mechanical shutter.
The Sigma fp uses an electronic shutter (sensor readout) exclusively for every exposure. There is no mechanical curtain, no shutter blades, and therefore no rated mechanical shutter life. This is similar to cameras like the Nikon Z9, but unlike the Z9, the fp's electronic-only design also means it has inherent rolling-shutter characteristics when photographing fast-moving subjects or panning under artificial light.
| Model | Release | Sensor | Shutter Type | RAW Format |
|---|---|---|---|---|
| Sigma fp | 2019 | 24.6 MP FF BSI CMOS | Electronic only (no mechanical) | DNG |
| Sigma fp L (high-res sibling) | 2021 | 61 MP FF BSI CMOS | Electronic only | DNG |
| Nikon Z9 (also no mech. shutter) | 2021 | 45.7 MP FF stacked BSI | Electronic only | NEF |
| Sony A7 IV (mechanical + electronic) | 2021 | 33 MP FF BSI | Mechanical + Electronic | ARW |
The Sigma fp stores shot metadata in its DNG RAW files. ShutterCount reads this data from the DNG EXIF block. Because the fp uses electronic shutter only, any count returned reflects total electronic exposures.
Without a mechanical shutter count as the primary wear indicator, used Sigma fp evaluation focuses on different factors:
| Check | How to Verify | Importance |
|---|---|---|
| Sensor hot/dead pixels | Shoot a dark frame at high ISO | Critical |
| Screen quality (scratches, dead zones) | Display white image, check corners | High |
| USB-C port condition | Check physically; test data transfer | High |
| Battery and contacts | Check runtime; inspect contacts | Moderate |
| Rolling shutter artifacts in sample files | Request DNG samples from video or fast motion | Moderate |
| Cosmetic wear on body | Visual inspection | Lower |
No. The Sigma fp uses an electronic shutter only. There is no mechanical curtain. This means there is no traditional rated shutter life and no mechanical wear from exposures. It is one of a small number of full-frame cameras with this design.
The Sigma fp shoots in Adobe DNG format (Digital Negative). It does not use a proprietary Sigma-specific RAW format. DNG files are directly compatible with Adobe Lightroom, Capture One, darktable, and most major RAW editors.
The Sigma fp uses a BSI CMOS sensor with a global reset but no stacked memory (unlike sensors in the Sony A9 III or Nikon Z9). As a result, it exhibits noticeable rolling shutter in fast-motion or panning scenarios. This is a known trade-off of the ultra-compact design.
The Sigma fp L (2021) uses a 61 MP BSI CMOS sensor (vs 24.6 MP on the fp) and adds a built-in electronic viewfinder (EVF) — a significant ergonomic improvement over the EVF-less fp. Both share the same form factor, L-mount, electronic-only shutter, and DNG RAW format.
Yes, within its constraints. The fp supports Cinema DNG raw video recording (via HDMI out with a compatible recorder, or internally at lower resolutions), Cine EI mode, 4K UHD up to 24p internally, and is compatible with ARRI Log C colour science. Its compact size makes it popular for gimbal rigs and cinema-style shooting. The lack of IBIS and the rolling shutter are the main trade-offs.
