This sale is for an excellent condition Mamiya RB67 90mm f3.8 lens, fully tested and in perfect working order.
This lens is mechanically perfect, and cosmetically excellent with just normal minor paint loss on the mount and knurled rings, as can be seen in the photos. There is some very fine dust inside the lens but otherwise no problems – no fungus, haze or scratches. Not quite optically perfect, but certainly nothing that will affect your images in any way.
