Originally posted by DSLRnovice Which 50mm lenses have the best reputation for edge to edge sharpness at middle apertures?
I took some really nice and sharp landscapes with M 50mm f1.7. I think all the f1.7 lenses are really sharp from f3 to f11. So sharp they would be hard to tell apart. So I think A, F, FA 50mm f1.7 are great choices; same optical lineage. M is good, too, but these days I recommend something with A on aperture ring.
DFA 50mm f2.8 macro is often mentioned as edge to edge sharpest 50mm lens.
That said, pretty much all 50mm lenses are acceptable at f5.6, many of them are already stunning by f2.8. Hard to go wrong. Sigma 50mm, Samyang 50mm, Rikenon 50mm,...
Of the 50-60mm lenses that I have, the M 50mm f1.7 is the sharpest, but the others are really super budget glass. If you spend over $75 you should get a good 50mm and if you spend over $500 it might be 10% better
