This is a nice Vivitar 28-210mm f3.5-5.6 PKA macro zoom lens to work on Pentax film & DSLR cameras in exceptional condition! The lens hardly shows wear and the glass opcits are also clean with no scratches, marks, fungus or dirt. It focuses and zooms smoothly and the aperture works properly with no problems. This is a sharp late model PKA lens with the "A" setting to work properly on the program mode on late model Pentax film as well as Pentax DSLR cameras! I have a money back return policy if not satisfied so buy with confidence. Shipping will cost $15 within the US or $25 for other international destinations.
