I am wondering how some of the older prime lens stack up against these?
When I have been researching into different lens in the past someone told me that one of the older Pentax prime lens was really exceptional. I'm not sure if it was an A or M lens but I'm certain they said that between the two that were available between the F1.4 and F1.7 the latter was the one to get as it was outstanding. Could it have been the Asahi Pentax-M SMC f1.7 50mm? And does anyone know what the difference is between the A and M designations? I also wonder if it is the case that the 1.7 was considered the better lens I am wondering what the reasons for that would be?
Thanks,
John
I have the M 50/1,4 M50/1,7, Fa50/1,4 A50/1,7
The M and A lenses are opticaly identical, but the A is just so easy to use.
All M and A lenses is better than the Fa 50/1,4. The Fa tends to flair.
BTW. Use a Lens hood, if not the 1,7 is bether than the 1,4 because the front lens is retracted a bit.
If you use a lens hood, its impossible to say which one is the best.
The Fa 50 is not as good as the M and A, even with the lens hood.
