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, Canon T8i has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 8 processor.
Below you can see the 7D MII and T8i sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 7D MII and Canon T8i Cameras
Canon 7D MII and Canon T8i 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
Canon T8i ,
including hyperfocal distance.
