Vignetting When Using Filters
I'm in the market for an ND filter. I use Rokinon cine lenses of which I have a 16mm and looking to get the 10mm. My question is will buying a larger nd filter and using a step up ring eliminate vignetting? The lenses have 77mm threads and was thinking about purchasing 82mm filters. Also, step up rings vary greatly in price ($5 to$30 or so), is there any real difference?
