TodwallnutsA nikon film 50mm 1.4 from at least 1990 or so is the sharpest lens I have ever shot with. Easily comprable to the Canon L series and it only costs about $50 plus a ten dollar adaptor.
It's easily sharper than any L-ZOOM lens, at least... I'd say the 135L or 85L would be far sharper (neither of the 50L's would be though.. those things are pretty dull and distorty - esp. the f1)
50$ would be a really good deal on a nikon 50 1.4 AI/AIS though... you're spending at least 120ish for a good copy if you really want that.
an older 1960's Nikon 50 f1.4 would be about 50-60$, but will flare a lot more due to more rudimentary coatings of the era.
Have a nice day, Bluename.
