Canon 7D MII has a
20.0MP APS-C (22.4 x 15 mm ) sized CMOS sensor and features DIGIC 6 (dual) processor. On the other hand, Pentax KF has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features PRIME MII processor.
One other difference between these two cameras that is worth mentioning is that Pentax KF's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the 7D MII and KF sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 7D MII and Pentax KF Cameras
Canon 7D MII and Pentax KF 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 7D MII
or the
Pentax KF ,
including hyperfocal distance.
