Asahi 28mm f3.5 Super-Multi-Coated Takumar lens mount_Mamiya 645 It features a microphone inputAsahi 28mm f3. 5 Super Multi Coated Takumar lens in excellent condition, with minor internal dust, no haze or fungus. A classic wide angle lens for M42 mount. This lens has a slightly longer rear flange which may interfere with full frame DSLR mirrors when used on an adapter, so maybe save it for your mirrorless camera if you're not going to shoot this on a Spotmatic.
