At any rate, here's what Rogliatti says in "Leica The First 70 Years". Pg. 158 "At Leitz the first computers were installed as early as 1951". I seriously doubt that those earliest computers were aiding in lens design much, if any. They probably were used in book keeping, inventory control etc. This surmise, on my part, is bolstered by Rogliatti's comment on page 162. "This period from the mid-fifties was also the beginning of the rapid advances in Leitz lens design, which have continued ever since, brought about by new optical glasses from their glass research laboratory and the application of computers". This time frame seems far more likely. -- Roger Beamon, Naturalist & Photographer Docent: Arizona-Sonora Desert Museum Leica Historical Society Of America INTERNET: beamon@primenet.com
