filter to fit two lenses
I have both a 72mm and a 62mm lens that I want to use a 10 stop ND filter on. I can't remember, should I buy the 62mm filter and a step up ring or the other way around? I tried the filter that fits my Cokin holder and sent it back because light was filtering in around it and it had a magenta hue. I want to try an actual screw in filter now.
