I'm thinking of getting an oly 40-150mm R lens and I like to keep my UV filters on the lenses for protection. I also like to keep a standardized filter size for most of my lenses. the one I generally use is 52mm and I was wondering if a 58-52mm step down with a UV filter would affect vignetting? I'd also like to use my 52-77mm step up ring with my cir-polarizer. It's a telephoto so I know it's less prone to filter vignetting but is stacking 1 step down ring, 1 step up ring, and one filter asking too much?
