Pentax Auto-Takumar 3.5/35
Pentax Auto-Takumar 3.5/35, with M42 screw-mount.
Really a cute lens, very small, the diameter of the filter thread is only 46 mm. In 1958 Asahi introduced its first camera with an automatically closing aperture, the Pentax K. So, the according lenses are called "Auto-Takumar", and actually they are only semi-automatic: you have to open the aperture manually with a lever on the aperture ring. This 3.5/35 was introduced in 1959 and has already a simplified lever.
This lens has a forerunner, the preset Takumar 4/35, which was the first Japanese 35 mm wide angle for a 35 mm SLR.
The design of this 3.5/35, 5 elements in 4 groups, was kept until the K-version from 1975 (later versions got the SMC coating of course). As I found out, this lens is appreciated by landscape photographers; stopped down it has a decent and homegeneous sharpness over the whole picture. So, probably this is no lens for bokeh addicted.
