Please read the profile and description before negotiating the price. This is a set of Nikon release buttons (shutter buttons). One is a genuine Nikon product, and the other two are made in Japan. The ones made in Japan have a slightly larger diameter, and I recall they interfered slightly during trial fitting. Please consider them as a bonus. I purchased these for my film camera (New FM2) a long time ago, but I sold the camera without ever using them. I believe the genuine Nikon product is a very rare item. It will be difficult to obtain in the future. What do you think? FM New FM2 Titanium TITAN FM3 FE Price reduction 3999→3850 (3/29)→3700 (3/30)
