I recently acquired a lens that is labelled: 'GOERZ DAGOR F:6.8 FOCUS 9 1/2 IN. No.222689' Can anyone identify what type of Dagor it might be and when it was produced? I've looked all over the WWW and can only find a 222*** Goerz series that appears far too old for this particular lens. The lens is coated but not multicoated and there is no country of origin marking on the lens it is in an Alphax shutter. It belonged to a photography professor in Rochester and it seems like a pretty nice piece of glass. The shutter would not be the orig.
Sanders is right: This lens is far too old for original coating and dates from anywhere between ~1906 and 1910; the shutter is at least 20yrs younger, likely a 1940s model. Re: 'What type of Dagor'?Just the 'normal' one., i.e. , or 'Gold-Dot,'.: This 72 degree Dagor (90 degrees at f 32) was sold as a 6.5x8.5' lens (wide open) which was however supposed to be able to cover 11x14' (!) at f 32.(Goerz 1913 catalogue). So, as a collectors item it ain't worth much, but that doesn't mean it can't be used to take nice pictures, which is also dependent on the shutter re-mount job, as cell spacing was critical with dagors. Thanks Thanks Everyone for your kind responses. I tend to agree with Phitz that this lens is likely from the 1950s and not the earlier part of the century. If B&J used their own serials, this might explain the variance and confusion.
The Holmes, Booth & Haydens lens above, is also marked 'Patented June 7th, 1859.' 'The Lens is almost 22' long including the shade. While on the subject of 'diffusion' or 'depth 'of focus it may be remarked that a delusion on this point is cherished by a vast number of photographers. For this the.

Click to expand.It's definitely not one of the infamous B&J 'Berlin Dagors'. Playhouse disney stanley animals game. Those lenses were assembled using old, loose, and often poorly matched, elements of dubious quality. They were sold by B&J as new 'Berlin Dagors' and did not contain the word 'Goerz' anywhere on the lens. If they would have, they would have been sued to high heaven by C.P. Lenses made in Germany prior to the German Goerz being absobed by Zeiss-Ikon (ca.
1926) are labeled: 'C.P. GOERZ BERLIN'. Lenses made in Germany after the Zeiss merger are labeled: 'Carl Zeiss Jena' and 'Goerz-Dagor'.

Crack cdbf dbf viewer and editor. Lenses made by the American Goerz company were engraved with a number of different designations over the years. The lens shown above is definitely a pre-WWII US made Dagor. The simple 'GOERZ DAGOR' was the engraving style they used at that time.
Later, possibly post-WWII, perhaps a little earlier (I'd have to comb though old catalogs to nail down a date), they switched to labeling their lenses 'C.P. GOERZ AM.OPT.CO'. This designation remained until around 1963 or 1964 when they changed the company name and labeling to read' 'GOERZ OPTICAL CO. And then there were the later Kern made Dagors during the Kollmorgen (early 1970s) and Schneider (1970s and early 1980s) years. Those are easy to tell as they are all labeled 'Lens made in Switzerland'. There may have been other permutations, especially in the very early years of the American Goerz company, but those are the main ones I know of off the top of my head. As I stated above, any Dagors assembled from loose elements by Burke and James are labeled as 'BERLIN DAGOR' absent the word Goerz.
The specific lens pictured in this thread is definitely decades older than the shutter it is presently mounted in. As others have stated, the shutter is not original. It's definitely a remount. Also, the date of manufacture of the lens pre-dates commercially viable coating technology by many years. So, if it is coated (it doesn't look like it is in the attached photo, but it's impossible to tell for sure form a small jpeg image), it was coated years later - possibly at the same time the lens was mounted in the shutter.
If it was retrocoated, the coating (and shutter mounting for that matter) may have been done by B&J. It may have been done by C.P. Goerz AM Optical, or maybe someone else. I have seen genuine Goerz lenses that were retrocoated by B&J.
I've even seen one in a box that contained a little slip of paper stating that it had been coated by Burke and James. Although coating reduces flare and increases contrast, uncoated Dagors are perfectly usable. The Dagor is a cemented design. So, it only has four air:glass interfaces (compared to an Artar or WF Ektar that have eight air:glass interfaces and benefit much more from coating). Click to expand.Ian, Thanks for the info. That date, right around the beginning if WWII seems about right for when the American Goerz started labeling things 'C.P. Stood for American.
The original C.P. Download Detective Conan Movie 13 The Raven Chaser Sub Indonesia here. Goerz was obviously a German company, and Goerz is a very German sounding name. So, here in the states, at that particular time in history, it would have been very wise from a marketing standpoint to make sure your potential customers knew you were an American company and proud of it. I also have what appears to be a pre WWII GoerZ Am. Optical Dagor, that is coated.
The inscription on mine reads Goerz Dagor, F:6.8, Focus 12 in., No. Mine is in an early Acme shutter. Any idea when this lens was made? There is a big gap in the listed Goerz serial numbers between 320000 (1918) and 751240 (1927). And if Burke & James were coating older Goerz Dagors.
How would they have done the actual coating? Coated the existing cells as they were, or de-cemented the cells, coated the outside elements and re-cemented the three elements in each cell?

Hi Jacque:To add to my friend's Sean's comments in reference to the C.P Goerz Berlin lens, a good friend of this page provided me with some guidance in selecting lenses for 8x10. Skype for windows 10 64 bit. And while some may seriously disagree, here is what he wrote on this topic:
--------------------------------------------------------------------- 'The Dagors are still popular due to their combination of small size and large coverage. Although the collectible market has driven up the prices in general, and especially for the Gold Ring, Gold Dot, etc. varieties, they can still often be found at relative bargain prices compared to equivalent modern glass. In some cases, there just aren't any modern alternatives that don't weigh 5x as much. In general, I have had good luck with Am Optical Dagors with serial number higher than 770xxx and Zeiss made Dagors from the 1930s - 1940s. Many older Dagors can also be quite good (but the quality seems to vary more), and I would avoid anything labeled as a 'Berlin Dagor'. These were assembled by Burke & James after WWII, and the glass used in them was horribly full of impurities. They obtained all these inferior old elements after the war as part of the liquidation of the German Goerz company, shipped them across the ocean, mounted them in barrels and shutters and sold them as 'Berlin Dagors' to distinguish them from the Dagors being made in this country by Goerz Am Optical (A separate company that had split off from the German Goerz sometime in the WWI timeframe).

All Goerz Am Opt. Dagors after 770xxx are of the same design and glass types. You can occasionally find very high serial number Dagors that don't have the gold rim or gold dot. They are every bit as good, and usually priced hundreds of dollars less. I have a suspicion that some of these were manufactured under contract for the US Military in the 1950s and 1960s. I have a 4 3/8' WA Dagor from 1961 that was originally part of a military field photographers kit that has a serial number above 800xxx, and it has a simple black barrel, even though I have an older 6 1/2' WA Dagor (786xxx) with the shiny gold rim and used to have a beautiful 12' Gold Rim Dagor with serial number 790xxx). Guess the military preferred the non-descript black barrels to the shiny brass ones of the Golden Dagors.
Good luck in your search for lenses for your 8x10. Other lenses to consider would be the Kodak Commercial and WF Ektars. They tend to be larger than the Dagors, and the Commercial Dagors have less coverage, but they are usually less expensive due to a lack of collector appeal. Also, in the longer focal lengths, the Red Dot Artars are great. They can be found occasionally in original Ilex shutters, but are more common in barrels (which can be re-mounted into Copal #3 shutters). I had a 16 1/2' Red Dot Artar that was my favorite lens when I used to shoot with an 8x10 Deardorff. Reasonably small, very sharp, and I just liked the focal length.' ------------------------------------------------------------------ I hope you and our other friends find this of interest.
