Just got a used smc PENTAX-FA 80-320mm f4.5-5.6 in Black but utterly disappointed that its faulty. No chance of return or refund.

No matter what the aperture setting is, including "A", the K20D and *ist DS show the "f" number blank so aperture cannot be controlled from the camera. I took a few shots mounted on the *ist DS and the camera shoots the lens either at f4.5 or f5.6 depending on the focal length. It is as if the aperture ring has no effect. Also, the K20D requests the focal length suggesting the contacts aren't communicating the lens information. However, pictures taken with *ist DS contain correct EXIF information about the lens.

I didn't really pay an arm and a leg for this so its not worth sending it in for repairs. Does anyone know of any tricks or have suggestions as to what might be wrong?

Thanks much.
