Thank you for viewing. ● Before purchasing, please be sure to read the [Notes] in the profile. This is the popular old lens "Early Model Super-Takumar F1.8/55mm," known for not using atom lenses that cause yellowing. It doesn't produce sharp images, but it creates a unique and rare flare! The optics are superb, and the exterior is in good condition! This is a recommended lens. The bokeh characteristic of old lenses and the flare at wide apertures (with samples) are first-class, and the sharpness when stopped down is excellent. The lightweight and compact body is not bulky, making it an outstanding lens that is also recommended for its ease of use. [Exterior] Superb Class Although there are some scuffs due to its age, it is a good product with no noticeable defects. [Optics] Superb Class: Superior Flare There is no mold or cloudiness in the lens, and although a small amount of dust is visible, the optics are very beautiful.
