i been thinking, maybe im wrong, but i think the crop factor does a lot to do with sharpness, i mean 50mm with crop is someting about 85 no?
ok for example with 50mmm , and i want to make a full body shot, I must get far from my subject as with a full frame camara. (sorry i dont know how to explain this my english kinda sucks)
crop factor = 5 meter from the subjet
full frame = 3 meters from subejt
does men that the full frame has more information of pixels and that mean more resolution?
what do you think??

Yes, all the full frame sensors have more information or pixels. But that is inherent in their design, and not a function of the crop factor.

What full frame sensors do have is the ability to fit the same amount of pixels on their surface as a smaller sensor, with a larger footprint for each pixel-site. Meaning higher light sensitivity for the same amount of pixels.

I don't think this really reflects sharpness though.
