I agree. There is not much difference in Pentax 50mm lens performance from the K50/1.4 thru M50/1.4, A50/1.4, and FA50/1.4. Same for the K50/1.7 thru M50/1.7, A50/1.7, and F50/1.7. I expect the same applies to the F50/1.4 and FA50/1.7, but I've never used those particular lenses (or even held copies of them). Regards, Bob S.
