Asahi Bellows-Takumar 100mm f4 brand_Slik carefree in the knowledge thatA classic M42 mount Asahi Bellows Takumar 100mm f4 lens designed for use with a bellows: this lens has no focusing system of its own, so it won't work directly on a camera. But on a bellows, it can focus from infinity all the way to 1: 1 magnification. In excellent condition, with light internal dust; diaphragm has a few marks, but moves well. PLEASE NOTE: This lens requires a bellows system (sold separately) for use.
