Thank you for the link. But I have to test the 50mm lenses in my own possesion. Of the mentioned Nikon lenses I own the 50mm/2 HC, a 50mm/1.8 longnose, a 50mm/1.2 AIs and a 50mm/1.4 SC. And I don't say anyone of these is bad.
But the copy variation in those old lenses and the further 50s of Minolta, C/Y, Olympus, Canon ... make me to choose my own favorite(s) for a general usability (less by evaluation in testcharts).
