I have acquired a Rokkor-X 50mm 1.4 Minolta MD as well as a Rokkor-PF 58mm 1.4 Minolta MC. On the GH2 they're a 100mm and 116mm. I conducted this test to help me determine which of them is the best performer. You can check my blog for a more extensive write up and my conclusions. Feel free to comment on which lens you prefer.
