Schneider-Kreuznach 21mm f/4 Super-Angulon R
The Schneider-Kreuznach Super-Angulon R 21mm f/4 is an ultra-wide-angle retrofocus lens with a 10-element, 8-group design for 35mm SLR cameras. At 350g with an M 72 filter thread, the R suffix denotes the retrofocus configuration needed for SLR compatibility. The complex 10-element design is required to achieve both the retrofocus back-focus distance and good wide-angle correction at this extreme focal length.
