hello,
got the basic glass now & am purchasing filters. my largest glass now is 77 (filter size). the wa lens is 75mm focal/67mm thread. will i get unwanted vignetting on the schneider SA 75 using a step up ring to the 77mm filter ? if so, would it still vignette w/ the step up ring & a slim filter mounted ? I am certain my movements will be further limited either way (am i correct ?), but want to keep my image circle as unobstructed as possible.
thnaks, jason
