But but ... there aren't any lenses, especially by Canon, that will resolve a 50MP sensor!!!!
I had an interesting discussion in a spanish forum on this. Can someone provide some evidence on that?
On my side I would assume that this new FF 50Mpx should put the same kind of "strain" on a lens than the 7DII, because of nearly identical pixel size, and I do get tack sharp pics on a 7DII (with some very high quality lenses)...it does not seem to me limited at all.
