This is the E55 form of the pre-aspherical 90mm Summicron-M, the later of the two filter sizes used on the third version; earlier lenses took E49. Production ran from 1980 to 1998 and totalled 29,853 lenses, with five elements in four groups by Walter Mandler, an eleven-blade diaphragm and a one-metre minimum focus. The E55 barrel is the shorter of the two at 77 by 63.5 mm, and in black it weighs about 475 g.
