The mysterious "Soft Focus" 150mm f4 lens for the RB67.
If you're a portrait photographer who's looking for that etherial glow in your portraits, this is the lens you want.
Included are ALL 3 inserts to vary the effects of the soft focus and edge diffusion. It is extremely rare to find all 3 inserts together. This is a beautiful lens that was recently overhauled and cleaned.
