Super-Takumar 55mm f/1.8 lens made by Asahi Opt. Co. - Model Name: Super-Takumar 55mm f/1.8 - Brand: Asahi Opt. Co. - Country of Manufacture: Japan - Lens Diameter: 55mm - Maximum Aperture: 1.8 This is an old lens, so there may be dust, haze, and fungus, but it should take pictures normally unless shooting into the light. The dust is not visible under normal fluorescent light, but tiny dust particles can be seen when illuminated by an LED. There appears to be no haze, but there may be some due to aging. There is some minor fungus. The aperture ring is smooth when opening the aperture, but heavier when stopping down. The focus ring is smooth. Please check the photos for scratches and wear on the lens barrel. This is a classic old lens, but please understand that it is a very old lens before purchasing.
