This lens was purchased new by me from KEH about 11-12 years ago. It's been used a handful of times and that's being generous. Comes with original box, hood, caps, and disk set.
Hi Alan, the front element(s) of this lens unscrews, and you can insert the disks to change the soft focus effect of the lens. Also, once you stop the lens down to F/8 and smaller, the soft focus effect is diminished and it looks like a regular lens, so you kind of get two lenses in one.
