Carl Zeiss Jena lenses for Contax after Thiele

Published in Spring 2006 Zeiss Historica Journal

Author: Sean McSharry

See Pages 19 – 21.

The author turns to the Thiele spreadsheets to help analyse the huge increase in manufacturing of photographic lenses during the late war years and the fluctuation of trained staff in light of the leaving of the temporary foreign workers, the loss of staff due to the staffing of the military, the loss of high level staff to Oberkochen, Russian 5 year contracts for workers to train new workers in Russia and their untimely return those 5 years later (circa 1951).

The new Cosina rangefinder camera with the Zeiss Ikon trademark opened the door for a new version of the F/1.5 Sonnar 50 mm T* lens which is more appropriate for a rangefinder than the SLR equivalent of the Planar lens.
