Selling my hard-to-find Vivitar Auto Telephoto Close Focusing 135mm f/2.8 macro lens with a Pentax PK mount. Note the Komine s/n 28708089 and 62mm filter threads; this version focuses down to 1:2 macro. It is a full frame lens and will mount on any modern Pentax DSLR body with no adapter required, including the K-1. It can also be adapted to other formats including mirrorless (no adapter included).

Glass:  Minor internal dust only. No scratches, no haze, no fungus. Very clean.

Cosmetics:  Some visible signs of previous use and wear as pictured, but good overall. 

Mechanics:  Aperture ring moves freely, iris is snappy with oil-free blades. The manual focus ring is a bit looser than average, but this does not impede normal use in any way. Zero issues and all functions work great.

Includes front and rear caps.

ADDED BONUS:  I will throw in a 2nd copy of this lens with an M42 Screw Mount for parts.  It has good glass but severe mechanical issues, the focus and aperture rings spin freely and don't engage at all.

If you disagree with anything stated above in regards to the condition of this item return it for a full refund.
