Canon 5D MII has a
21.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic 4 processor. On the other hand, Z CAM E2-F6 II 6K has a
24.6MP Full frame (35.9 x 24.0 mm ) sized CMOS sensor .
Below you can see the 5D MII and E2-F6 Mark II 6K sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 5D MII and Z CAM E2-F6 II 6K Cameras
Canon 5D MII and Z CAM E2-F6 II 6K 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 5D MII
or the
Z CAM E2-F6 II 6K ,
including hyperfocal distance.
