Thank you all!
I also have the M50 f1.4 (and 2 copies of the A50 f2:The Rodney Dangerfield of primes) Actually, about 90% of the pictures in my museum blog are with the M50 f1.4 But the benefit of the A setting makes the 1.7 more convenient to walk around with, at least for me. Having AF capabilities can probably make it the only lens in my camera.
Stopped down there is little difference between both. But in my non-scientific and subjective tests and opinion, I "think" the 1.7 is a hint better overall, especially below f5.6. But I admit the 1.4 "looks" gorgeous
Now the f1.2 would be a dream to have. Focusing the 1.7 and the 1.4 wide open is not that easy, I imagine the 1.2 would really require skill and practice.
dgaiers, the P3 was cleaned and tested and it seems to be in perfect shape. I plan to take it on a quick trip to a local natural reserve. I'm just hoping to have the time to do that soon.
Thanks,
