Hello all:
Am wondering about black and white filters for Schneider 90mm SA-XL. I am confus ed by conflicting advise I have received from dealers. I am choosing between B+W and Heliopan. Do I have to have special "wide" or "thin" filters for this lens? One dealer told me that I needed "special" filters or they would touch the glas s of the front element.
I am also planning to use step down rings to use these large 95mm filters with m y other lenses which have 77mm and 58mm filter sizes. Is it nuts to try to go do wn this far (58mm)?
Thanks!
