Auto-Takumar 1:1.8 f=55mm Asahi OPT. CO., Japan

The main differences from other models of the Auto-Takumar 1: 1.8 / 55 series

1. The case is made in black-and-white style, like "zebra"
2. The lens has 10 aperture blades
3. Near the front lens is the name “Auto-Takumar 1: 1.8 f = 55mm Asahi O.P.T. co., Japan“, rather than the more familiar “Auto-Takumar 1:1.8final match. ASAHI OPT. co., Lens made in japan"
4. Different body design: no window for focusing distance. The distance is marked on the focus ring. The aperture control ring is located near the front lens. There is a large control lever on the bayonet side
5. The lines of the depth of field scale are bent and go at an angle
6. The aperture control ring is marked from F / 22 to F / 1.8 (when looking at the lens from above, when the lens is directed with the front lens away from us). Subsequent Takumar 55 / 1.8 lenses closed the aperture only up to F / 16
