21.0MP Full frame (35.9 x 23.9 mm ) sized CMOS sensor and features Expeed 6 processor.
Below you can see the 5D MIII and D6 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 5D MIII and Nikon D6 Cameras
Canon 5D MIII and Nikon D6 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 MIII
or the
Nikon D6 ,
including hyperfocal distance.
