Hi Darryn,
My SMC A 50/1.7 also has a sticky aperture ring - not as sticky as yours sounds
though. In comparison, my (what looks like older) SMC M 50/1.7 has no such problem.
I think it stems from the fact that the newer A series lenses have plasticky aperture
rings. Unfortunately, the A70-210/4 and the A50/1.4 have plasticky aperture rings
too. The A24/2.8 is pure magic - feels like a piece of "real" camera gear.
I was disappointed that the A50/1.4 had a plastic aperture ring. I have fears that it
might become sticky with time like the A50/1.7. Maybe I'll have to get an A50/1.2 to
have a "real" piece of camera gear and A series coatings at the same time.
Is the A50/1.4 really optically that much better than the M50/1.4? I'm not sure if
I'd rather have a lens that feels better to use at the price of optical performance.
Yours sincerely,
Frank.
