Classic 90mm wide-angle for 4x5 large format in compact Copal No.0 shutter mounting.
The Schneider Super Angulon 90mm f/8 is a classic wide-angle large format lens for 4×5in cameras, mounted in a Copal No.0 shutter. The 90mm focal length is one of the most widely used wide-angle lengths in large format photography, providing a moderate wide view equivalent to approximately 28mm on full-frame with a large enough image circle for useful camera movements.
90mm focal length, f/8 maximum aperture, Copal No.0 leaf shutter, large image circle (approximately 216mm at f/22) covering 4×5in with movements, standard large format lensboard mounting.
The Super Angulon 90mm is a reference wide-angle for 4×5in landscape, architectural, and environmental photography. It is one of the most common large format lenses in the second-hand market, ensuring reasonable parts availability and broad user experience. A centre filter is sometimes used to compensate for corner fall-off. Competes with the Rodenstock Grandagon 90mm and Nikkor SW 90mm.
Verify all Copal No.0 shutter speeds operate correctly (1 second to 1/500s, T, and B). Inspect all elements for fungus, haze, and coating condition. Confirm lensboard compatibility with your view camera. Check aperture blades for oil contamination. Test shutter cocking and cable release port.
