no, i don't have the current one. i have a 15-30. i'd say that any Sigma lens that provides a rear filter holder will vignette at least moderately with any filter you can put in front remotely close to 82mm. you will have to go much larger than 82mm not to have that happen. however, since you are interested in film use, 20mm is pretty wide and there are lots of choices there where you can put filters in front. there is no way to put a filter in front of the 15-30 on a film camera without severe vignetting. on the *istD, only a slim filter won't vignette enough to matter. a regular filter vignettes a lot and you can forget the Cokins. if you can find the Tokina 17mm manual focus prime, it's not too bad and you can put a 67mm filter on it.
