Actually I don't quite get it yet, but using any of the available DOF calculators online, they tell me the DOF for a given focal lenght, aperture and subject distance is smaller/shorter in APS-C than for 35mm (?). Anyone care to explain? I thought DOF was shorter for larger formats.
You seem to have forgotten to also increase the focal length correspondingly. And it is more complicated than this because image quality is involved as well (by the increase in both sensor and lens areas). There are various threads in this forum discussing this at length, with mixed conclusions
This thread here, I would say, isn't the place to carry on this discussion
