The EDF also contains a detector for active infrared sources. Notes on the identification, numbering and annual and individual production of early Carl Zeiss Binoculars (1894 1907 ) 5 th Edition Prologue The current study supersedes my very first attempt at. The EDF was built in 2 versions: The standard EDF 7x40 was equipped with a radioactive reticle illumination, the EDF 7x40 oB without illumination. Carl Zeiss engineers came up with a more compact roof-prism design, employing a split doublet objective and a five lens ocular construction. The DF in NVA and Grenztruppen service was an optimal performer for watch tower surveillance but at 1.2 Kg, a challenge for soldiers to carry around under combat conditions. Overall a very good general condition with a few small paint damages.Item condition: used, but with visible cosmetic markingsWichtiger Hinweis zur.

Carl Zeiss engineer's main aim in the EDF design was to build a binocular with same qualities as the DF, but at a lower weight and smaller size. Carl Zeiss Jena Binoculars Jenoptem 7x50 W, GDR, Multi-Coated, serial No. Rare vintage Carl Zeiss Jena DF 7×50 Artl Nr97 G military Binoculars. The EDF 7x40 was designed as the successor of the DF 7x40 and introduced in 1981. It was forbidden for East German soldiers to rest the DF 7x40s on vehicles, indicating some measure of their value and the resources involved in manufacture. The DF binoculars were to be carried according to NVA regulation "at the man".
The DF in service use, featured a leather strap attached to the central joint of the binoculars so the DF could be fastened to the soldier's uniform so there was some measure of stability while the soldier was moving. The eyecups are made of soft rubber and fold in so that the binocular can be used with gas-mask or glasses. These yellow filters are stored inside the of the plastic ocular cover. (the design was also later used by Carl Zeiss Jena for some models) Zeiss Oberkochen initially made their individual focus 7x50 design from 1956 to 1961. There are yellow filters for use under hazy weather conditions. This allowed the objective body (the large cylindrical part attached to the front of the binocular) to be shorter than usual. The DF features an extremely robust and armored body, a ranging reticle which can be illuminated by a battery powered device and a detector for active infra-red sources, which is charged by the UV contribution during daylight. The DF is regarded by experts as the finest binocular ever made in Jena.
Zeiss Oberkochen initially made their individual focus 7x50 design from 1956 to 1961.The DF 7x40 was produced during the 1960s/70's by Carl Zeiss Jena for the East German NVA. (the design was also later used by Carl Zeiss Jena for some models) This allowed the objective body (the large cylindrical part attached to the front of the binocular) to be shorter than usual The West German models included what’s called a tele-objective, where the 2 big lenses on each side of the binocular, were not glued together but spaced apart However, when the West German company commenced in 1954, it used new more compact designs The East German company recommenced production using pre-WWII designs and equipment a seperate company at Oberkochen in West Germany one at the original location of Jena, in what was then the new nation of East Germany (and continuing to use the original ‘Carl Zeiss Jena’ marking), and The binoculars are made by Zeiss and are post-WWII productionĪfter WWII, there were two Zeiss companies in operation:
