How to determine the production year of a Leica lens based on the serial number
It is produced and hosted as another way of expressing gratitude to those who have helped Company Seven prosper. With some of this content dating back to the times when slow dial-up Internet access was the norm, the article was originally text heavy because illustrations were by necessity kept simple and to a minimum. Over the decades we have, and will continue to, on occasion add this or that mention of or illustration of items in our archives and museum collection, this to break up the monotony of text, make corrections with much gratitude to Dr. It was never our intent to write one comprehensive and all-encompassing history of Zeiss, that would require volumes to do it justice, but rather to explain why we at Company Seven remain grateful for and in awe of the achievements by Zeiss. From its inception through to the middle 19th century, lens making was a craft that was essentially passed on from generation to generation. Innovations had typically resulted from trial and error experimentation; this was a costly and time consuming process that could not factor in all of the possible variables in lens making materials and design. It would be left up to one who could employ scientific methods of study, and then devise the mathematical formulas to characterize the physics of optics to make the next important technological leaps possible. It would then be asked of a chemist to invent and manufacture those raw materials necessary to make the new designs possible. And it would be one man to bring this combination together to create a concern of unrivaled accomplishment. Carl Friedrich Zeiss 23, bytes.

The other day I was surfing the bay in a 7×35 binocular search and found there were dozens of old porros from the golden era of Japanese porro production. Back in the days of the Japan Telescope Inspection Institute, when all the binoculars were actually inspected and received a little golden sticker. We were reaping rewards from that process such as few of us likely appreciated. Anyway, my curiosity got the best of me, and I bought one.

The German Zeiss binoculars which were seized from a U-boat commander after his surrender Lt Elliott wrote in the vessel’s visitor’s book of his ‘great pleasure’ at being the first British seaman to board the captured U-boat. Both the binoculars and the book were handed down to his son Tony Elliot, who also went to to serve in the Royal Navy and became a commodore before retiring.

They were produced in such a huge number that you can still buy a pair of these in good condition second-hand and the price, ranging from about 50 to Euro, is quite affordable. We were motivated by curiosity how a set of binoculars, produced over 20 or 30 years ago, compare with those currently manufactured; we also deeply believed that they were still able to outperform contemporary instruments made in China.

Which Binoculars can your Repair As far as I have been able to find out pretty much any pair of binoculars can be repaired. You get some companies that specialise in niches like wartime and vintage binocular repairs and then obviously if you have a newer pair that is still under warranty you can get it repaired or even replaced by the manufacturer or distributor themselves. Zoom type binoculars can also repaired.
Which Faults can be Repaired Again pretty much every problem can be repaired from collimation problems to even modifying some binoculars to focus closer. Once opened to be repaired, your waterproof binoculars can then even be re-sealed and purged again with zero grade nitrogen to ensure that they remain water and fogproof by some of the better repair companies. Binoculars can also be serviced, where they will be completely stripped down to be thoroughly cleaned both inside and out, new lubricants put on all moving parts and then sealed up once again.
