This sale is for a Mamiya RB67 50mm f4.5 C lens in mint condition. It is of course in perfect working order, including flash sync and mirror up.
This lens is mechanically perfect, in beautiful condition, with absolutely minimal signs of use. The lens is virtually unmarked, with just a couple of really tiny paint chips on the knurled locking ring. It has perfect glass. I have used this lens for a few shots and it is absolutely fine.
This is the latest C type multicoated lens – much better optically than the earlier pre-C single coated optics.
Unless you do something daft like dropping it, it will outlast just about any other piece of photographic kit out there. These lenses are just made to keep on working and working – no electronics to go wrong! And you won’t find a better example than this one.
