This 55mm f/1.2 lens, made by COSINA in Japan, boasts high descriptive power. I feel like there might be some slight haze, but I haven't really noticed it while shooting. I don't think there are any scratches because I always used a filter! I don't think there's any visible mold either! - Brand: COSINA - Model Name: 55mm f/1.2 - Filter Diameter: 58mm - Aperture: f/1.2 - f/16 - Country of Manufacture: Japan Thank you for looking.
