This German made super wide angle is primarily for a 2x3 film size camera. It can cover 4X5 with a recessed lens board. The F.O.V is approx. 120 degrees. Sharp lens to the edge. It is mounted in a Synchro- Compur shutter with speeds B - 1/500 and firing on all. Included are lens cap, 49mm B+W UV filter, mounting ring and trip cable. All in great condition. I no longer own the camera I used it on.
