Fujifilm XF10 has a
24.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor . On the other hand, Sigma DP2 Quattro has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS (Foveon X3) sensor and features TRUE III engine processor.
Below you can see the XF10 and DP2 Quattro sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm XF10 and Sigma DP2 Quattro Cameras
Fujifilm XF10 and Sigma DP2 Quattro have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Sigma DP2 Quattro has 22% larger pixel area (18.81µm 2 vs 15.37µm 2 ) compared to Fujifilm XF10, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Fujifilm XF10
or the
Sigma DP2 Quattro ,
including hyperfocal distance.
