This is a Super-Takumar 135mm F3.5 (M42 screw mount) that came with the PENTAX SPOTMATIC. The Super-Takumar series is a popular classic lens, highly regarded for its: * Excellent color reproduction * Soft and natural bokeh * Charming, characteristic rendering of old lenses The 135mm focal length is easy to use for portraits, snapshots, and playing with old lenses on mirrorless cameras. It comes with a black leather-type dedicated case, making it suitable for storage and collection. --- 【Condition】 * Appearance: Scratches and minor imperfections commensurate with age * Inside the lens: No noticeable mold or significant clouding is observed (※ Please forgive any minor dust particles, as this is an old lens) * Case: Shows signs of use (no problem for practical use) ※ Within the scope of a simple check with my available equipment, I did not feel any significant operational issues. ※ This model is also popular as an entry-level old lens. --- 【Important Notes】 * This product is NOT a PENTAX K mount. * It is an M42 screw mount. (※ Can be used with mirrorless cameras, etc., by using a conversion adapter) ※ Due to the nature of old lenses, we cannot guarantee the same performance as a new product. Please purchase only if you understand the nature of vintage items.
