There are some very small specs on the rear glass element coating, visible only under certain angle of view and lighting conditions. This does not impact lens optical performance whatsoever. There are few small, usual dust specs inside the lens.

Focusing is buttery smooth, aperture blades are oil-free and snappy in A- Mode. M-Mode works great.

Original Pentax font and rear lens caps, matching metal hood in Mint shape are included. Also included is original leather lens case in somewhat aged, but very nice shape.

Please see photos.

Use it on Pentax M42 mount cameras, digital K-Mount Pentax cameras with M42 to K-mount adapter, or various mirrorless cameras with an appropriate adapter.
