This is a great little wide-angle lens for your Pentax screw mount camera or any body that has the M2 mount. The glass looks good, it focuses smoothly and the aperture ring moves easily. The lens body is in good shape and it comes with front and rear lens caps and a nice Tiffen Yellow 12 filter to enhance those blue skies and clouds when you shoot black and white film. I'm selling this on consignment in my shop in Amherst, NH so if you're interested in it buy it now before it sells locally. As it's a consignment item there is no flexibility on the price.
