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 NEX-5T and DP2 Quattro sensor size comparison.
Sensor Size and Resolution Comparison image of Sony NEX-5T and Sigma DP2 Quattro Cameras
Sony NEX-5T and Sigma DP2 Quattro have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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
Sony NEX-5T
or the
Sigma DP2 Quattro ,
including hyperfocal distance.
