Really S3 2000? Where?
I should add that whether or not it adds to the price, the Millennium Nikkor is one of the 50mm lenses that does a fairly good job of covering the corners of the new Sony A7 full-frame sensor. (A7 is said to work better with RF lenses than A7r, so I haven't tried the latter). Millennium Nikkor offers no color shift in the corners, even at wide apertures; and corner smearing almost disappears as you stop down from f1.4 to f4. So maybe S3 2000 and Sony together (with adapters) make a useful 50mm analog/digital pair?
(Can't say the same, unfortunately, for the classic f1.4 5cm Nikkor. No color shift, but it produces soft corners with flare and smearing from f1.4 to 4. Much better on digital Leica than on Sony.)
