This is lens is beautifully crafted and has a unique feature: the name “Mamiya” is engraved on a ring around the center of the lens barrel which makes this lens look very classy.
The lens can be found here and there on the used market. For a mint one you usually have to invest at least US$ 100 based on my observations.
I was a little bit disappointed by the optical performance of this lens. Another Mamiya collector has told me that he was very impressed with the performance, but according to my tests it is not as good as the 135 mm lens.
