Pentax K lens - Sears (Tokina) 75-260mm F4.5

Good lens for landscapes, backyard birding, macro and portraits. Constant 4.5 aperture.

Very sharp lens. Clean glass. Excellent close focus mode. All metal construction. Built in hood. Includes filter but no front cap.

This is a manual focus lens. The aperture must be set manually as well. If you have a Pentax camera, no adapter is required. If you have a Sony, Canon, or Nikon FF or APC camera, an adapter is needed. Aperture is set manually. If you have M4/3 camera (Olympus, Panasonic) you will need an adapter
