A mid-to-long auto-focus tele-zoom for Pentax with variable aperture. Priced to move. Mostly plastic build, but solid. Compact and not too heavy to shoot hand-held. A good walk-around lens. Zoom ring gets a bit stiff at the long end. Focus ring does not stick at any point throughout the turn range. Glass is very clean. No haze or fungus. I purchased a 70-200 with constant aperture and this hasn't seen much use since. Time for someone to get a deal.
