Hmmm intrigued. I just ordered a minolta 55mm f1.7. I have to imagine it\'s better than my Om50 f1.4. Those look pretty sharp!
I think sebboh mentioned that in his tests it was the sharpest Minolta lens for closeups but others were better at longer distances. I haven\'t tested the lens, but my images look sharp enough for f/1.7 with a lens from 1970.
fyi.
Auto Rokkor, Rokkor, Minolta MC/MD 1,8/55mm (1958) - 2/55mm (1959) - 1,7/55mm (1966) - 1,9/55mm (1971) and the latter 1,7/50mm MC/MD (1977, the final evolution) adopt same scheme (double gauss 6 elements and 5 groups, first triplet not cemented), in the years wearing different and always better coatings and minimum focus (from 0,5mt to 0,45mt).
Don\'t alsost all medium fast 50\'s adopt that scheme?
There are two mechanically different versions of the 1.7/55, the younger one from 1970 has an elevated focusing ring (in German we call them mountain and valley, I don\'t know the correct English term), the older one from 1966 has a flat one. Oh and the close focusing distance ot the 1.7/55 is 55cm, I think Dennis Lohmann\'s list isn\'t correct there but I reported that already.
