Pentax K-7 has a
15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features Prime II processor. On the other hand, Canon 700D has a
18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 5 processor.
Below you can see the K-7 and 700D sensor size comparison.
Sensor Size and Resolution Comparison image of Pentax K-7 and Canon 700D Cameras
Pentax K-7 and Canon 700D 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
Pentax K-7
or the
Canon 700D ,
including hyperfocal distance.
