The Asahi Auto-Takumar 35mm f/3.5 is an early wide-angle prime from Pentax's Takumar series in M42 mount. The Auto-Takumar designation indicates auto-aperture coupling. At 35mm f/3.5, it provides the classic wide-angle perspective at a modest aperture. Part of the legendary Takumar lens family that defined quality M42 optics.
