Protar VII Plastigmat Dagor How they differ from each other.

... and especially to the OCTANAR, made by O.Simon, Dresden. The last lens was patented 1902 by DRP 168 977. ...

I have a very fine little O. Simon Anastigmat of about 210mm focal length which is a very good performer indeed. I don't know whether it's an Octanar or not, but I can have a go at counting reflections

Let us not forget we also have 'Zeiss Goerz Dagors'.

Uniquely both Schneider through their purchase of Goerz Am. Opt and Zeiss with the amalgamation of Goerz, Berlin, still have rights to manufacture Dagors.

Yes, when Goerz became part of the Zeiss combine when it took a bushel of marks to buy bread. But nothing changed to the lens.

Lets start a letter campaign to Kyocera in Japan. I don't see why modern dagor's would be expensive to make. Still, the Cooke XV is probably a benchmark of what the price would need to be in the numbers saleable for modern production.

[Ian Grant]

Wrong company Kyocera never made LF lenses & sold their interests to Sony. Cosina perhaps, but they are quite canny and I doubt would be interested in tooling up for LF lenses.

More seriously if someone could make modern Dagor's, and also some of the Protar designs like the f18 EWA they would be useful. Now if Cooke were to re-enter the field with a small light weight wide angle for 10x8 and upwards the'd have a captive market.

I think Kyocera has all the Zeiss rights. They made the tessar on my little Yashica T4.

They DID have a license to make Zeiss branded optics for their Yashica and Contax cameras, but they are out of the photography end of the business. They still make cell-phone optics and photo-copiers. The license if still valid, will eventually expire. This is why Zeiss (in Germany) calls its current 35mm RFDR camera (made by Cosina) a Zeiss-Ikon, rather than a Contax. Cosina makes many of the Zeiss branded lenses in "M" mount, as well as the Zeiss lenses now available for 35mm SLR format film and digital cameras, under license from Zeiss, with Zeiss manufacturing and quality-control equipment. Zeiss still makes lenses in Germany, also.
