Summary
The 35mm F3.5 M42 screwmount lens was introduced in 1959 as an Auto-Takumar and the optical design remained unchanged all the way to a K-mount version. The Auto-Takumar was followed by the Super-Takumar which came in three variants. Finally the 35mm F3.5 was released in a Super-Multi-Coated version. The 35mm F3.5 thus came in a total of five M42 versions plus the K-mount version. The three Super-Takumar versions can easily be distinguished from each other:
First version: Smallest F-stop is F22.
Second version: Smallest F-stop is F16 and the distance scale has no “window”.
Third version: The distance scale has a “window”.
