Asahi Pentax Auto-Takumar 55mm f/1.8 with lens cap!
These lenses were introduced in 1958 for use with the Pentax K camera, the improvement was the semi-automatic aperture system, consisting of 2 rings. One ring sets the aperture and the other is a spring-loaded ring that keeps the aperture fully open for focusing. When pressing the shutter halfway, the camera pushes a pin on the rear of the lens closing the iris to the set aperture and have DOF check, then fully pressing the shutter takes the picture. The lens remains closed until the shutter is cocked for the next exposure. In this generation of lenses, the only known lens in "Zebra" finish was produced (Auto-Takumar 55mm/1.8).
