Nikon P7700 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor . On the other hand, Ricoh GXR S10 24-72mm has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CCD sensor and features Smooth Imaging Engine IV processor.
Below you can see the P7700 and GXR S10 24-72mm F2.5-4.4 VC sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon P7700 and Ricoh GXR S10 24-72mm Cameras
Nikon P7700 and Ricoh GXR S10 24-72mm 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 S10 24-72mm has 20% larger pixel area (4.16µm 2 vs 3.46µm 2 ) compared to Nikon P7700, 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
Nikon P7700
or the
Ricoh GXR S10 24-72mm ,
including hyperfocal distance.
