This might be a stupid request but I've lost my Nikon D50 manual (well not really lost, I'm sure it's still somewhere in all that chaos, so I better say "tempoary not findable") and this is kinda desperate (ebay ;-)). So could someone please look if the manual 28mm f/2.8 AI-s lens will be compatible with the D50? AI-s should usually be working but I remember that there was a list with lenses in there which were incompatible anyway. Mhm, maybe another question to the owners of that lens: Is it really that good? I've only read about exceptional sharpness and great performance and the like and it sounds almost too good to be true. Will it be significantly better than the D50-kit lens (18-55) at 28mm?
