Canon R has a
30.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features DIGIC 8 processor. On the other hand, Canon R6 III has a
32.5MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic X processor.
Below you can see the EOS R and R6 III sensor size comparison.
Sensor Size and Resolution Comparison image of Canon R and Canon R6 III Cameras
Canon R and Canon R6 III 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 Canon R has 13% larger pixel area compared to Canon R6 III, 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
Canon R
or the
Canon R6 III ,
including hyperfocal distance.
