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, Ricoh GXR A16 24-85mm has a
16.0MP APS-C (23.6 x 15.7 mm ) sized CMOS sensor and features Smooth Imaging Engine IV processor.
Below you can see the GXR A12 50mm F2.5 Macro and GXR A16 24-85mm F3.5-5.5 sensor size comparison.
Sensor Size and Resolution Comparison image of Ricoh GXR A12 50mm and Ricoh GXR A16 24-85mm Cameras
Ricoh GXR A12 50mm and Ricoh GXR A16 24-85mm 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 Ricoh GXR A12 50mm has 31% larger pixel area compared to Ricoh GXR A16 24-85mm, it has potential to collect more light on pixel level hence 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
Ricoh GXR A12 50mm
or the
Ricoh GXR A16 24-85mm ,
including hyperfocal distance.
