Mamiya made very good 35mm cameras,but, the company never considered them their prime product and did a very poor job of promoting them. By the way, everyone knows that the Nikon FM10 is made for Nikon by Cosina. Did you know the Nikkorex was made for Nikon by Mamiya? They also sold it to Ricoh where it was known as the Singlex, and to Sears but I don't remember Sear's name for it, I think it was the TLS. All three were in Nikon F mount.
