SUMOM 11102 is the M bayonet version of the 21mm f/4 Super-Angulon, built for Leitz by Schneider-Kreuznach from 1958; roughly 5,292 went out in M against about 1,462 in screw thread. Guenther Klemt's nine element, four group computation covers 92 degrees, with full click stops to f/22, a nine-blade diaphragm, a 0.4 m close focus and A42 or E39 filter fittings. The chrome-plated brass barrel is remarkably compact at 51 by 27 mm and 250 g. Framing is done with an accessory 21mm finder.
