Schneider-Kreuznach Super-Angulon — 65mm f/5.6 wide-angle lens for 4x5in view cameras
The Super-Angulon 65mm f/5.6 is a wide-angle staple of Schneider-Kreuznach's large-format Super-Angulon line, positioned between the extreme-wide 47mm and more moderate wide options for 4x5in view camera work, and is the faster, larger-coverage version of this focal length.
It follows the series' symmetrical Biogon-derived construction, built as a barrel lens for mounting in a Copal shutter and fitted via a lens board rather than a bayonet. Coverage extends past 100 degrees, giving generous movements for architectural and product photography on 4x5in film.
Compared with the slower 65mm f/8 version in the same range, the f/5.6 design gives a brighter ground-glass focusing image and a larger image circle, at the cost of extra size, weight, and a bigger front filter thread.
It is a commonly used wide-angle among working large-format photographers, so used supply is reasonably steady. Check shutter speed accuracy, confirm aperture blades move freely without oil, and inspect for the front-element coating wear and minor scratches typical of a well-used wide lens.
