It is *not normal* in the newest Kobalux 21mm (I can't speak for the older ones Adorama sells, both because it has a different optical formula and because I don't have one), and that's part of why the front element is so big. I can send you the full-frame scans if desired. See ourworld.compuserve.com/homepages/dkieltyka/Kobalux21.htm for a discussion of the extremely low level of vignetting in the new lenses. If you use a Tiffen or B+W filter even the new ones will vignette. Stick to Hoya or a thin-ring B+W. Dante > Hi everyone, > I just test a roll of film on my leica M6 TTL with Kobalux 21mm lens.
