Sensor Size and Resolution Comparison image of Ricoh GXR GR Lens A12 28mm and Ricoh GXR S10 24-72mm Cameras

As seen above, Ricoh GXR GR Lens A12 28mm has a 8.9x Larger sensor area than Ricoh GXR S10 24-72mm. 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 Ricoh GXR GR Lens A12 28mm or the Ricoh GXR S10 24-72mm, including hyperfocal distance. One thing to watch when comparing these two: they have different sensor sizes (APS-C versus 1/1.7-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.
