I've been looking at getting a variable ND filter but.....I have 3 lenses with 3 different thread sizes and cant really afford 3 filters
My question is.. Can I just buy a 77mm filter, then use adapter/reducing rings for the other two lenses (67mm and 62mm) or will that not work?
Lenses in question are....(all Sigma)
70-200 f2.8 (77mm)
17-70 f2.8-4 (67mm)
30mm f1.4 (62mm)
I won't use the filter on the 70-200 very often but don't want to rule that out by getting a smaller filter (67mm)
Cheers in advance.
