Tamron Adaptall 200mm f3.5 BBAR MC with Pentax K-A mount 7 with smooth focusing and diaphragm

with smooth focusing and diaphragm action and only very minor internal haze

7 is a zoom lens for C mount cameras (or cameras with C-mount adapters)

and won't work with full frame EF cameras

That's the joke

Tamron Adaptall 200mm f3.5 BBAR MC with Pentax K-A mount 7 with smooth focusing and diaphragmThe Tamron Adaptall 200mm f3. 5 BBAR MC (model 04B) is a reasonably fast telephoto lens with an interchangeable Tamron Adaptall mount (a Pentax K A mount is included). The barrel claims "Close Focusing" and, while you're not going to mistake this for a macro, it does focus down to 1. 7m, which is not too bad for a 200mm lens. Clean glass, minor cosmetic wear, smooth focusing.
