Used: 1.5X Mutar for Rolleiflex with bay ii filter mount (bay 2)
The Mutar is an auxiliary lens that fits onto your TLR and makes it either a telephoto or wide angle version. This is the 1.5X version which gives you a telephoto view and will fit on TLR's with bay 2 (baj ii) filter mount - please see table below for Rolleiflex models.
Condition: Glass is excellent, and the mutar mounts well to the camera. Leather case (good value by itself) is in good condition with some wear marks and discoloration. There is a tiny flat on the bottom front edge near the filter mount. I do not know if will affect fitment of filters over the Mutar or not, but I think not.
