Canon R50 has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic X processor. On the other hand, Canon 7D MII has a
20.0MP APS-C (22.4 x 15 mm ) sized CMOS sensor and features DIGIC 6 (dual) processor.
Below you can see the R50 and 7D MII sensor size comparison.
Sensor Size and Resolution Comparison image of Canon R50 and Canon 7D MII Cameras
Canon R50 and Canon 7D MII have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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 R50
or the
Canon 7D MII ,
including hyperfocal distance.
