Hi Herb, It's for film. I haven't been fortunate to be digital enabled yet. About filters, wideangle and vignetting, I know you probably won't be able to stack more than 1, but the filters I'm looking at have slim versions for wideangle, so I'm assuming that if there is vignetting, it'll be minimal. You say the newer Sigma 17-35- have you got experience with the current one (82mm)?
