Tokina SD 70-210mm f4-5.6 Zoom Macro Lens Pentax K Bayonet Japan.

This lens is in very nice cosmetic condition, however it has some mechanical issues that likely render it unusable:

1) The aperture won’t adjust when the lens is fully extended.

2) The lens appears to have been disassembled and some of the tiny buttons on the rear of the lens are missing. Also, there are some marks on the various glass lens retainer’s.

3) We don’t see any fungus or haze, but there are some light dust particles on the interior surfaces of the lenses.
