My first real camera lens was a 50mm1.4 Rokkor MD sitting on the front of an XD-11 camera. Nice setup, I am sure whomever stole it got good use (or money) out of it. It was replaced by a SRT with a 1.7 and I didn't notice any difference in sharpness of image, there in my formative days. As a matter of fact, the ONLY Minolta equipment I have been unhappy with was a XG body with a 50mm 2.0 lens on it I think. Junk. I gave it all away and bought my FM2 with incomparable Nikor glass in it. Never looked back. I think you will be happy with either the 1.4 or the 1.7,
