Ricoh GXR A12 50mm has a
12.0MP APS-C (23.6 x 15.7 mm ) sized CMOS sensor and features GR engine III processor. On the other hand, Canon EOS C70 has a
8.9MP Super 35 (26.2 x 13.8 mm ) sized CMOS sensor .
Below you can see the GXR A12 50mm F2.5 Macro and C70 sensor size comparison.
Sensor Size and Resolution Comparison image of Ricoh GXR A12 50mm and Canon EOS C70 Cameras
Ricoh GXR A12 50mm and Canon EOS C70 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
Ricoh GXR A12 50mm
or the
Canon EOS C70 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus Super 35),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
