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. The Founders And The Zeiss Company Foundations: 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.

Few original Zeiss anastigmats seem to actually carry this T.N. as a result of the date, which was after some had ceased production, but Protar is still a correct.
And Zeiss had beaten it by more than a full stop! This was an era when lens speed was critical. Film was slow, and high speed lenses allowed you to take pictures in lighting circumstance that slower lenses were not going to capture. It’s interesting that although they took an early lead, this was to be the fastest lens they ever built. It was also a lens with good performance, you really didn’t sacrifice anything except some hard earned cash with this lens over one of it’s slower brothers.

Here is a number of Carl Zeiss designated Versuch experimental lenses from to , possibly the first time in over 60 years that so many original “V-lenses” have been assembled in one place at the same time.
Several Versuch and other prototype lenses from the Goerz lens collection, which Carl Zeiss eventually absorbed, including Dagor and Celor variants, and a very unusual Quarz Anastigmat for ultra-violet light. Here are two influential wide-angle designs from the Zeiss collection. On the left is a legendary Carl Zeiss Sphaerogon 1.

Two original Decmeber prototype production Weitwinkel wide-angle variants, fully finished in polished brass barrels, of Dr. Paul Rudolph’s landmark anastigmat design, in mm and mm focal lengths, with wheel stops. The following year, the initial catalog versions of this lens were decidedly lighter and more compact.
Comparing and matching the many unique experimental optics in the collection that lack any proper identifying mark other than occasional lead or grease pencil data, small optical diagrams, and engineering shorthand with actual references within the Zeiss documentation presented a daunting and time-consuming task. However, patience and tenacity were rewarded.

Hello to the community, as a youngster to this very special forum, I am coming up with a marginal problem. When was this one produced? As far as I understand, Carl Zeiss Jena introduced lens coating T some time in , but not covering the whole production, and after the coating process was declared “eyes only” and attached to military purposes, mainly with the German marines, so that very few if any coated lenses reached the wartime civilian market.
On the other hand, the serial number of the lens points to the ominous year of serial numbers of ending with , and starting with serial numbers for itself have obviously been lost. So, is this one wartime or post-war? Material is brass, not aluminium. It’s not of REAL impotance to me, but it’s to do a bit with family history. Hey you people in the U. Anybody thought of what might have been photographed with these vintage cameras? Apart from that: Any ideas on the lens?
I’m pretty certain this is post-war. It is a very nice lens with a very good design, and it looks like it’s in good shape. I have a russian copy, and it’s a darn good and sharp lens

This Praktisix II was manufactured between and , but the Tessar lens shown here was last produced in the Praktisix mount in February It would have been fitted to the original version of the Praktisix. The makers of the Praktisix decided that the camera would sell better if it had the option of a more prestigious standard lens than the four-element Tessar, although we should not forget that at the time the first Hasselblads were also being supplied in many markets with a Tessar lens.
However, the Meyer-Optik Primotar continued to be offered as an economical alternative for a number of years. The first 80mm Biometars for the Praktisix had the same cosmetic style as the Tessar illustrated above — mostly alloy, with a black leather focussing band. However, some of the lenses later in the same production run! The lens illustrated on the right here was part of that first production run.
It rather looks as though the manufacturers used up their stocks of leather bands before starting to use the plastic rings with the bumps — or perhaps the plastic rings were a component that was not ready at the beginning of the production run, a situation that regularly occurred in the post-war years in East Germany. Pentacon Six brochures produced in and show lenses with this finish.
One brochure also shows lenses with this finish, but the lenses must have been taken from earlier production runs, as the mostly-black lens style with a leather band on the focussing ring had entered production in — see the next section. With rough handling it could easily crack or work loose, so a return was made to a leather band.

Zeiss gathered a group of gifted practical and theoretical opticians and glass makers to reshape most aspects of optical instrument production. His collaboration with Ernst Abbe revolutionized optical theory and practical design of microscopes. Their quest to extend these advances brought Otto Schott into the enterprises to revolutionize optical glass manufacture. The firm of Carl Zeiss grew to one of the largest and most respected optical firms in the world.

The Hasselblad series began with the revolutionary C, one of the most iconic cameras in photographic history. Modified throughout the years, the series cameras represent the pinnacle of Victor Hasselblad’s V System. With multiple prototypes in the works in , the final Hasselblad C was launched in Replacing the previous design of a focal plane shutter from the F, the C utilized a leaf shutter design with its range of high-quality Carl Zeiss lenses.
Its leaf shutter design allowed for flash synchronization at all shutter speeds with the use of electronic flash. It could also focus at full aperture thanks to an automatic aperture stop-down.

The lens proposed here with the main statements of his patent, registered in April , is small in size and was originally fitted to a mahogany wood plate; the barrel is made of burnished brass and, as usual, the stopping-down references for the iris actually indicate the diaphragm hole in millimeters; notice how the data in the front ring are manually carved, removing the black lacquer and displaying the bare brass.
The lens features a pleasant vintage appearance, showing all its years; on the side of the barrel can be seen the
