WW1 Imperial German Navy – 6×30 MARINEGLAS BINOCULARS – ZEISS – SUPERB!

 The German Army used a wide variety of optical equipment, including a 6×30 (6 power magnification with 30mm objective lens, being the standard issued optics used by all branches of service).  Though this type was the standard, specialized personnel required stronger optics (such as this 10×50), and were issues to personnel on a limited basis.

The Zeiss “Marineglas” is the military version of the civilian Silvamar model, with similar characteristics. It is the first binocular model with 30mm lenses. The device turned out to be very successful, with high aperture ratio, plasticity and large field of view, that is why it became popular in the army. The Marineglas was produced from 1907/08 and up to 1917 with various modifications. Later the binocular name was changed to D.F. 6×30.
