I sold my Oly 45mm and PL45 because I just don't use this focus length much at all. I already have an FD50mm 1.4 for occasional portraits. I want to purchase a 50mm 3.5 macro for my (very occasional) macro work. I have adapters already for both. My question: I tested my FD50 vs. Takumar 50 vs. OM 50mm 2.0 macro perviously (have since sold the latter two). I found the OM to be sharpest, the Takumar to have the best bokeh, but the FD to have the better color and contrast. So, I've stuck with the FD. My one issue with the my bayonet FD is that the focus ring is not buttery smooth like either my Takumar or my OM were. Because of this, it can be fiddly when you get down to fine focusing (like when you are shooting wide open). Is this typical of FD mounts? Do they have sub-standard focus ring action? Maybe it's just the bayonet mounts, and the breech mounts are smoother? Maybe I just have a sub-standard FD copy? Any help is appreciated, as I'd like to get a 50mm macro, and want to know if I'll be OK with another FD and if they are SUPPOSED to have better focus rings, maybe I'd even replace my 50/1.4 with a different copy. Thanks for any insight.
