Asahi Auto-Takumar 1,8/55mm "Zebre" | Analogue camera

"Rare" Asahi Pentax Auto-Takumar 55mm f/1.8 M42.

Although designed for M42 screw-mount cameras.
The lens has six elements in five groups, takes 46 mm filters, has a semi-automatic diaphragm and was produced for only a short period between 1958 and 1959. It was designed for the Asahi Pentax K and is the only Pentax lens with a distinctive zebra pattern on the focus ring where the flats between the knurls are highly polished/chromed. The meter and feet scales are white.

Aesthetically, the lens is in moderately used condition with a few minor scuffs and light scratches on the chrome areas. The engravings are clean and nicely filled with white. Focus is smooth and the aperture ring turns well with positive stops. The chrome semi-automatic aperture actuator lever works as it should and has a good return-spring action.

Part of my collection that I am currently reorganizing.

The iris blades (there are 10!) snap shut when released and show only very minor wear in the form of a few bright marks. The aperture can be set manually as long as the actuation lever is not engaged. The optics are in excellent condition – no fungus, no unpleasant scratches.
