Vignetting would occur equally at all corners, so, unless you have a very odd lens and filter, you've probably not experienced vignetting. I've not experienced the problem using B+W filters on my lens, and I believe B+W filters are a little thicker than the Hoyas. You didn't say whether or not you were using a lens hood.
Of course, if you had a lab process the film, it's possible that they clipped off some of the image. Take a look at the negatives to see if there's vignetting at all four corners. If not, then it's possible that something blocked the lens. -- Shel Belinkoff mailto:[EMAIL PROTECTED] http://home.earthlink.net/~belinkoff/ Scott Nelson wrote: > > I just got my first roll of pictures back after buying this lens, and the > two shots I took with it are vignetted in one corner (completely black, not > just dark).
