msweeney Posted September 10, 2009 Share #1 Posted September 10, 2009 Advertisement (gone after registration) Just a curiosity really... saw this item for sale on ebay: a Leitz 7.5cm f/0.85 lens? Never heard of it in the books before so I was wondering if anyone else knows about it. Maybe it was for some military application or other? I've only heard of a 90mm f/1 lens up until now... boy Leica has made some amazing stuff. ~ Mike Link to post Share on other sites More sharing options...

luigi bertolotti Posted September 10, 2009 Share #2 Posted September 10, 2009 I think it used to be a lens for X-Ray apparat - wartime years or around ; Lager displays a similar item in his book on lenses, I seem. This item probably comes from factory museum... the seller seems to have arranged some kind of business with them and, time to time, puts for sale some of these fascinating oddities. (Lager displays some monster of this kind, but for photo use, like a Hektor 280 2,8, and even a catadioptric 600 or 800...) In the linked page it is shown mounted on a M body... nice to see but I suppose one cannot take any decent pic with it - not a standard photo lens, I think.

lars_bergquist Posted September 15, 2009 Share #4 Posted September 15, 2009 The 7.5cm Summar 1:0.85 was created in 1934, but it was a special purpose lens, not for general photography. I do not even know for certain if it had the standard 39mm mount. During the 1936 Berlin Olympic Games it was used --- now don't drop your pants --- for TV projection. TV in 1936? Yes, Virginia, and in Britain too at about the same time. The war delayed the development for consumer use until after 1950. In Berlin, goings-on at the stadium were televised and relayed to a press room some distance away. A picture of the front end of the lens is in Theo M. Scheerer, Leica und Leica-System, 2nd edition, Frankfurt a. M. 1960, p. 57. The old man from the Birth of TV Link to post Share on other sites More sharing options...
luigi bertolotti Posted September 16, 2009 Share #5 Posted September 16, 2009 Thanks for the info Lars... I made a mistake about X-Rays... ; do you know if the book you quote can be found somewhere ? Link to post Share on other sites More sharing options...
lars_bergquist Posted September 16, 2009 Share #6 Posted September 16, 2009 Only second hand of course. You may try Lindemanns Foto-Buchhandlung (http://www.fotobuecher.de/) but a search for Theo Scheerer gave no hits. That old man Link to post Share on other sites More sharing options...

lars_bergquist Posted September 22, 2009 Share #9 Posted September 22, 2009 I should warn you that the amount of factual info that Scheerer gave on this lens is very small, in fact close to non-existent. The book was not a technical handbook by any means. The old man from the 1930's Link to post Share on other sites More sharing options...
