adan Posted March 8, 2012 Share #2  Posted March 8, 2012 It is complex, because while Leica has one head of the optical department at any one time, there are numerous designers working in the department who may be the real or primary designer of any one lens.  E.G., Erwin Puts credits an unnamed "young woman designer" with doing the adaptation of the 35 Summicron ASPH design from the existing 35 Summilux ASPH.  The 21/24 Elmarit ASPH lenses predate Peter Karbe's reign as chief designer (appointed 2002), and were created while Lothar Kölsch was the chief designer - but Karbe worked in the department prior to running it, so he may have had a hand in the 21/24.  Karbe worked on an "ASPH" 50 Summicron in the 90's - which turned out to be too expensive (for an f/2) to build, but formed the basis for his 50 f/1.4 ASPH.  The lenses designed under Kölsch (1986-2002) include: 90 Summicron AA, both the Aspherical and ASPH 35 f/1.4, 35 Summicron ASPH, 28 Elmarit E46, 135 APO-Telyt, and most of the later APO R teles (180 APO f/2 and f/2.8, 280 APO f/4, 400 f/2.8 APO, modular 280-800 system, 105-280 zoom).  Kölsch's c.v.: http://www.koelsch-schroeder.de/english/k_s_optical_engineering/l_koelsch.html Link to post Share on other sites More sharing options...
