i'm gonna complain about something dumb i did. my first (for a long time only) lens was a ligma 60-200 in AF mount with a 52mm filter thread, and my second was a 35-70/4 kit zoom with a 49mm thread. when i started buying filters i standardized on 52mm, and i didn't know any better at the time, but i definitely regret it now: all the Minolta AF glass after ~1990, and all the SR mount glass before ~1975, is 55mm--so all the cheapest and most common glass, and all the super interesting glass, is in a filter size i can't reasonably adapt to. if i could do it again i'd standardize on 58mm or 67mm or whatever it is the 20/2.8 uses (72?), but as it stands i'm stuck with some pretty nice color, ND and CPL filters in a restrictive size
