From 1958 onwards Schneider-Kreuznach produced the 21 mm Super-Angulon for Leitz. The 4/21 mm Super-Angulon, introduced in 1958, is a nine-glass construction in chrome finish and was available in screwmount and bayonet-mount. Its successor was the eight-element f3.4 lens, which was produced in chrome and black finish in bayonet-mount. At the 1980 Photokina Leitz introduced its own 21 mm lens, the Elmarit f2.8. The offered six lenses are prototypes or samples by Schneider, all differing from the serial production models, with Schneider rear caps and in perfect condition. Schneider-Kreuznach fertigte ab 1958 das 21mm Super- Angulon für die Firma Leitz. Das 4/21 mm Super-Angulon hatte neun Linsen und war in verchromter Ausführung als Schraubobjektiv oder mit M-Bayonett erhältlich. Der Nachfolger war das acht-linsige 3,4/21 mm Objektiv, in verchromter oder schwarzer Ausführung, mit Bayonettanschluss. Erst auf der Photokina 1980 wurde das eigene Elmarit 2,8/21 mm vorgestellt. Die sechs angebotenen Objektive sind Prototypen oder Muster von Schneider, alle unterschiedlich zu den Serienobjektiven, mit Schneider Rückdeckeln und in perfektem Zustand.
