Older Carl Zeiss 10x50 binoculars puzzled owner (1 Viewer)

Until about 22 years ago, Leica did offer eyecups for their older binoculars with a little bit of rubber which folded down. Here is a set on an 8x30 Binuxit.

I very much appreciate the knowledge imparted by the contributors of this forum group as I was completely ignorant of the depth of the options available by European optics manufacturers. I use miniaturebonoculars.com as a regular reference guide (thanks to Mark Ohno)- another valuable reference resource . Regards, Pat

Hi,

Zeiss West serial numbers are not consecutive and also not the same as the (consecutive) CZJ numbers, so even the production numbers per year for Zeiss West as listed in that web page shown above don't help.

You need somebody with access to the records, like Gary... maybe he'll help to find the date for the 10x50 Jahrhundertglas #516585.

It probably is before 1971 or past early 90s due to the use of Made in Germany which was replaced with made in West Germany after the London Agreement in 1971.

Just received a reply from a Phd at the Zeiss archives. He basically stated the serial numbers do not run consecutive and this makes pinpointing a manufacture date difficult. The best he could offer was that the 10x50 oberkochen production ran from 1957 until 1969. The question still exists but I need a nap at this point. Thank you all for your input.

@Pinewood - IIRC you are fortunate in that those rubber eyecups allow you to use your Binuxit with glasses? There is something enjoyable about using binoculars straight to one's eyes and I appreciate the more "immersive" view whenever I have to (as with most of my old porros), but I have to admit that if a binocular permits me to use it with my glasses, I do.

Yes.

Certainly

Hello Patudo,

I can use a binocular without my glasses if it provides enough focussing travel, which does not always occur, but only if full daylight, when pupils "stop down." At night my astigmatism is much more pronounced.
When I had an old Porro B&L overhauled, I did get it set so that I could focus to infinity without my specs.

Happy bird watching,

An isolated, and perhaps irrelevant fact.

At 2000 EDT today, at 40.8 N latitude, under a cloudless but slightly hazy sky, I could see significantly more detail in shadows under trees with an 8X30 than my naked eyeballs. (which just saw dark holes)

I have no way to measure how bright it was then, so this is just an anecdotal observation, offered in view of all the discussion of binocular performance in “fading light”.

Sunset was at 2028 EDT.
