Tamron Adaptall 200mm f3.5 BBAR MC with Pentax K-A mount brand_Yamato and there is no adapterThe 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.
