Asahi Optical Co. Auto-Takumar 55mm f/1.8-16.0

Despite the name, this version of the 55/1.8 had build in full auto-aperture, just like the later Super Takumars. It differs from the previous Auto Takumar 55/1.8, produced in 1958, only in the mount and the aperture mechanism. This version was discontinued in 1962.

The optical construction of this version is the same as the original Auto Takumar 55/1.8 with the Semi-Auto Aperture control
