Canon R7 has a
33.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor and features Digic X processor. On the other hand, Ricoh GXR P10 28-300mm has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Smooth Imaging Engine IV processor.
Canon R7's sensor provides 23MP more than Ricoh GXR P10 28-300mm's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the R7 and GXR P10 28-300mm F3.5-5.6 VC sensor size comparison.
Sensor Size and Resolution Comparison image of Canon R7 and Ricoh GXR P10 28-300mm Cameras
As seen above, Canon R7 has a 11.7x Larger sensor area than Ricoh GXR P10 28-300mm. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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
Canon R7
or the
Ricoh GXR P10 28-300mm ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus 1/2.3-inch),
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.
