This vintage Mamiya -Sekor C 90mm f/3.8 manual focus medium format lens is for use with Mamiya RB67 Pro S and SD. At some point, someone either tried to forcefully mount or unmount this lens which resulted in a small bend in the mounting flange (please see photos). It does mount, but it is very annoying and not easy to get off. There are also a few scuffs and scratches on the exterior of the barrel. All settings adjustments are smooth and all shutter speeds sound correct. There is an extremely light haze inside of the lens, but it is free of any fungus or separation to its elements.
