Given the same quality of optics ...

There is a small problem with that assumption. You want the same relative quality, i.e., the smaller lens to project a scaled down image with no loss of detail. It is not happening. As much as I like Noikia's 808 41 mp small sensor, their phone cannot beat a 40mp MF system. Also, it cannot do, say f/4 FF eq., and as such it is more prone to diffraction since its lens (it goes to something like f/7-f/8, the crop factor is about 3.5).

Nokia 808 vs. Pentax 645. Almost the same pixel count. The same resolution, right?


The MF shot is at 40mm eq., and the Nokia - at 28mm. He moved a bit to get similar framing for some of the elements.
