hkItem Name : Dallmeyer Kinematograph 75mm f1.9 Prototype
Serial no. :
Reference : Here's an outstanding Dallmeyer 75mm f1.9 experimental lens, No.2 Kinematograph 7.5cm f1.9 came after that,below with pictures compare both lenses,no engraving on front rim,only hand engraved on side without serial no.,aperture ring turn position opposite,an exceedingly rare Versuch or prototype lens made by Dallmeyer,later acquired and studied by Carl Zeiss Jena (read more about that below). Another outstanding opportunity for serious historians and collectors of Zeiss and related lenses and the evolution of optical technology, or for modern photographers seeking the most exotic and interesting pieces.this lens originated in the C.P Goerz patent and prototype lens collection that was absorbed in 1926 by the even more famous Carl Zeiss lens collection, the massive accumulation of over two thousand pieces that Zeiss maintained in Jena across five decades, preserving all their prototypes and design variations from their beginnings in 1888 through the 1940's, and including hundreds of important and influential optics from their many competitors as well. The collection was brought to America by the United States military in 1945 just before Jena fell into Russian control, then after a few years of research under the Signal Corps it was handed over to Burke & James in the early 1950's for safe keeping in their own "lens bank", until eventually in the 1960's-1970's B&J (now Burleigh Brooks) sold it off in bits and pieces to the public.
