Sony A7 has a
24.0MP Full frame (35.8 x 23.9 mm ) sized CMOS sensor and features Bionz X processor. On the other hand, Canon 6D has a
20.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic 5+ processor.
Below you can see the A7 and 6D sensor size comparison.
Sony A7 and Canon 6D 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.
