This is the rare 135mm f2.8 K mount internal focus lens. It is prized for its image quality and must have some serious glass inside because it is surprisingly heavy.
This lens is in good condition with moderate wear. There are a few fine marks on the front element, but they will not affect your image quality. Otherwise it has clean scratch-free glass and works perfectly. Cosmetically, there is moderate wear with no damage.
The lens caps are included.
