This is a Distagon 60mm lens for the Applanix DSS medium format digital camera. It's a tuned-up version of the Distagon 60mm that Zeiss provided for Hasselblad and other cameras, making it quite a rare item. I intended to modify the mount and use it someday, but it's been stored away for about 10 years. I'm offering it to someone who can use it. There are some scratches on the exterior, but no noticeable gouges or major damage; it's in good condition. The lens is also clear. A filter and rear cap are included.
