This is the SMC PENTAX-M 35mm F2, a single-focal-length vintage lens from Pentax. It's a single-focal-length lens that produces images with a rather modern feel. I purchased this used, as a set with a body, in a new, unused, and extremely beautiful condition, but I ended up hardly using it, so I am putting it up for sale to declutter. ☆I believe this is a beautiful item, rarely seen at this level of quality☆ [Appearance] ◎Regarding the appearance, it is a beautiful item with no noticeable scratches. ⇛I believe you will be able to use it comfortably. [Optics] ◎Regarding the optics, it is a beautiful item with no noticeable scratches or mold. ⇛I believe the light transmission is good. ☆Although I have confirmed all the operations, I am selling it as junk because it is a vintage lens. Please purchase it with the understanding that it is a used item. - Filter size: 49mm - Mount: Pentax K mount - Release year: Around 1977
