Drop an X3F RAW file from your Sigma dp0 Quattro to check the shutter count — processed entirely in your browser, never uploaded anywhere. The dp0 Quattro is the widest camera in the dp Quattro series, featuring a unique 14mm f/4 lens (21mm equivalent) and the Foveon X3 Quattro sensor.
Check Shutter Count →The Sigma dp0 Quattro (2016) is the widest and last-released camera in the dp Quattro series, adding a 14mm f/4 ultra-wide lens (21mm equivalent on APS-C) to the lineup that began with the dp1 in 2014. It shares the same Foveon X3 Quattro sensor and distinctive elongated body design as the other dp Quattro models. The ultra-wide perspective makes it particularly suited to architectural, interior, and expansive landscape photography. Sigma does not publish a rated shutter life for the dp0 Quattro.

| Actuation Count | % of Est. Life | Assessment |

The dp0 Quattro is predominantly used for deliberate, tripod-mounted photography. Per-session shot counts are typically low, so a 9-year-old body with only 15,000 actuations is entirely plausible. Prioritise inspection of the lens element (front element scratches significantly degrade wide-angle performance) and Foveon sensor condition alongside the shutter count.
The dp0 Quattro uses the same Foveon X3 Quattro sensor as the rest of the dp Quattro family — APS-C size (23.5×15.7 mm), with 19.6 MP at the top silicon layer (capturing blue-green wavelengths) and 4.9 MP at the two deeper layers (capturing green and red). The asymmetric Quattro architecture delivers approximately 29 MP effective detail while improving processing speed and high-ISO performance compared to the earlier symmetric Merrill generation.
The 14mm f/4 lens is an 11-element, 8-group optical design specifically optimised for the Foveon sensor's light-incidence sensitivity. The f/4 maximum aperture is slower than the f/2.8 on other dp Quattro models, a necessary trade-off for covering the ultra-wide 21mm equivalent field of view at compact dimensions while maintaining edge sharpness. The minimum focus distance is 22 cm.
Yes. Sigma embeds a shot counter in the X3F RAW format EXIF block. Drop the X3F file into shuttercount.app and the actuation count is displayed immediately. This works for all dp Quattro and SD Quattro models — the X3F format reliably embeds the counter, unlike Panasonic RW2 files.
Covering a 21mm equivalent field of view (14mm actual focal length on APS-C) with an f/2.8 aperture in a compact body would require a significantly larger and heavier lens element. Sigma chose f/4 to maintain the dp Quattro's characteristic slim profile. For the primary use cases — architectural and landscape photography — f/4 is rarely a constraint, as a tripod is typically used anyway. Depth of field at 21mm f/4 is very generous even at moderate distances.
The dp0 Quattro is one of the finest tools available for architecture and interior photography when used within its constraints. The Foveon sensor produces straight lines with exceptional crispness and zero moiré or colour fringing from demosaicing — a genuine advantage for capturing tiled surfaces, window frames, and structural details. The 21mm equivalent field of view is wide enough for most interior spaces without the extreme perspective distortion of a 16mm or wider lens.
Sigma Photo Pro (free) provides the highest-fidelity rendering for X3F files and is the only software that fully exploits the Foveon architecture. Adobe Lightroom Classic supports X3F import but processes it through a standard demosaicing pipeline that does not honour the three-layer capture data correctly. For critical results, use Sigma Photo Pro for RAW development and export to TIFF for further editing in other software.
Both cameras share the same 29 MP effective Foveon X3 Quattro sensor and body design. The difference is purely optical: dp0 offers a 14mm f/4 (21mm equiv) ultra-wide perspective, while dp1 provides a 19mm f/2.8 (28mm equiv) moderate wide angle with a one-stop aperture advantage. The dp1's f/2.8 makes it more versatile in lower light; the dp0's 21mm is uniquely suited to architecture and vast open landscapes. Neither camera is better overall — the choice comes down to preferred field of view.
