I have a new-in-box Pentax SMC DA 50-200 mm F/4 lens for sale. This is the weather resistant version that allows you to shoot in inclement weather and conditions without worrying about lens failure. Works with all modern Pentax digital SLR cameras, I'm selling only because I switched cameras for work. Includes front/rear lens caps, lens hood and carrying case.
