The most diffused opinion in this list is that when using 35mm
lenses on APS-C cameras you get wider DOF, while Pentax states that
you get narrower DOF. Isn't it interesting?
Here's how it goes:
If you use the same focal length lens, the DOF is DECREASED on the
16x24 format due to the smaller CoC.
If you use a lens of comparable Field of View, the DOF is INCREASED
due to the smaller lens opening at the marked aperture settings.
