The Wollensak Apochromatic Raptar 10.25" f10 is a large format lens suitable for use on an enlarger or a camera- but there's no shutter, so keep that in mind if you're going the camera route. In excellent condition, with minor cosmetic wear, light dust, very minor haze behind the front element. Includes a threaded mounting ring. Covers up to 4x5; the focal length is about 267mm, if you're not down with the inches.
