Hey—I love it when others come to the same conclusions, with regard to lens performance, as I do. I also found the MC Rokkor-PF 50 mm 1:2 one of Minolta's best standard lenses ever. It is at least as good as the MC Rokkor-PG 50 mm 1:1.4 (which is Minolta's best high-speed standard lens), if not even slightly better.
However the MC 50/2 was not immediately followed by the MD Rokkor 45 mm 1:2—there was a short-lived MD Rokkor 50 mm 1:2 following the MC 50/2 and preceding the MD 45/2. It was the very same lens as the MC 50/2 but with an updated MD aperture mechanism. After the MD Rokkor 45 mm 1:2 came the MD 50 mm 1:2, without the 'Rokkor' name, which must not be confused with the previous MC and MD Rokkor 50 mm 1:2 lenses.
By the way—did you know that Minolta made a metal screw-in hood specifically for the MD 45/2? It was not delivered together with the lens but a separately-sold accessory, so it's extremely rare in today's used market.

I guess there's a reason why there's a rumour that the Minolta MC Rokkor-PF 50 mm 1:2 actually is
the Leitz Summicron-R 50 mm 1:2 glass in a Minolta barrel. I don't know if it's true—probably not but it could be. It was the time when Leitz and Minolta closely co-operated, the lenses' performance is virtuall equal, and also the lens element formulas match—six elements in five groups, with the cemented group behind the aperture. In 1976, Leitz switched to a new design for the Summicron-R 50 mm lens (now six elements in four groups) ... so maybe they generously let their co-operation partner have the old 6/5 design ...
