I still don't buy into this argument. First of all, it's not
logical; just because a lens doesn't exist in a certian mount
doesn't mean it CAN'T be made. Nikon had a 300mm f2 -- no such
thing from Canon, at least not in their EF mount. Does that
mean they couldn't? No. By extrapolation, does it mean Nikon
could do a 50/1.0? I don't know.
Until someone shows me an equation that says for a given focal
length and max. aperture your rear element MUST be so big, I'll
have no reason to believe that Nikon CAN'T make a 50/1.0.
