This is a fairly rare portrait lens fof the 645 system with a ring on the front to dial in the amount of softness. Soft focus is different than out of focus; it projects a slightly out of focus image over a sharp image, which reduces edge contrast without removing resolution. The effect works best with a light subject against a dark background, where it gives a halo effect. The lens is in clean condition with clean scratch-free glass and works perfectly. Caps are included.
