Pentax K-500 has a
16.0MP APS-C (23.7 x 15.7 mm ) sized CMOS sensor and features PRIME M processor. On the other hand, Pentax K-r has a
12.0MP APS-C (23.6 x 15.8 mm ) sized CMOS sensor and features Prime II processor.
Below you can see the K-500 and K-r sensor size comparison.
Pentax K-500 and Pentax K-r 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.
