    Opaque and greenish view

    Yes, a 6x24. Symbol has been rubbed but if examined closely under a strong light it is still entirely visible. Obliterating Nazi symbols I can understand but this one not so much. Even with the marking obliterated it is obviously still a military binocular.

    Opaque and greenish view

    This is mine. Optically in fine condition with a nice view. Note the brass eyecups. The Ü.K. stamp, though, is in poor condition. Yours is superb, far better than average.

    Opaque and greenish view

    Look carefully at the pictures of the eyepieces. Note that there are filter cups installed on each eyecup. This will account for a great deal of the lens colouration. Also, the photographs have an excessively green colour balance distorting the actual appearance of the binocular. So I’d say...

    Cataracts and binoculars

    I had cataract surgeries in February (right eye) and March (left eye) with Toric lenses due to astigmatism and have experienced dramatic improvements in vision, i.e. greatly improved brightness, colour fidelity (no longer any yellow hued views like looking through Soviet binoculars all the...

    Engravings German WW1 naval binos

    This marking on WWI and 1920’s period Leitz Porro II binoculars has baffled collectors for quite a while. It has been discussed on the Binopedia Forum with no resolution, and if anybody would understand what it means, I think somebody there would. For what it’s worth I believe that during the...

    Kershaw undated binoculars

    These WWII period British No. 2 Mk II’s remained in service for many years after the war probably until at least 1979 when the Avimo 7x42 was introduced and were serviced and reconditioned many times during that period. On your example the original cover plates have either been replaced or the...

    Finnish Army binoculars

    Looks like a German 1930’s -WW2 Dienstglas 6x30 (standard infantry binocular) made by at least a dozen different makers including Zeiss, Leitz, Busch, Voigtlander, Swarovski, Hensoldt etc. The binocular was a close copy of the Zeiss commercial model Silvamar 6x30 introduced about 1910. The...

    Inside a vintage German "Hanseat" 8x30

    Those prism wedges are just like the ones in the 3 or 4 Hartmann Berninas I’ve had. My guess is that you are correct and the bino was made by Hartmann. Prism wedges like that, though, are not new. Goerz used them on some binoculars before WWI and the Belgian OIP’s had them during the 1950’s...

    Hungarian military binoculars 6*30

    It almost surely was made by Magyar Optikai Müvek (Hungarian Optical Works) usually known as MOM which had a long history and made among other things respectable quality military optics as well as civilian model cameras: Once a world-famous factory in Budapest, now a hardly known company - The...

    How many types of Porro prisms?

    As far as I know Zeiss, Ross and Barr & Stroud were the only manufacturers ever to cement a field lens to a Porro II prism in order to reduce the number of air/glass surfaces thereby increasing light transmission and reducing stray light. The Zeiss examples were mostly 7x50’s and marked H for...

    How many types of Porro prisms?

    The real difference in Porro I and Porro II prism systems is the geometries of their light paths and not whether the prisms are cemented or not. Most but not all Porro II arrangements have cemented prisms but there are some examples of air spaced Porro II arrangements, and most but not all Porro...
