Soviet GOI Summicron Copies- Orkideja and Merkurij 52 -20mm - Where to buy ?

[Mustafa Umut Sarac]

These are 1950s Summicron Copies , Glasses reaches to 1.667 or more. St Petersburg made. 20 and 52mm. 20mm is so interesting for me it reeaches 120 lp/mm at the center but fast to drop at the corners.

Where to look for buy online - not so in love with ebay for such a old lens - ?

Is there any user , photographs ?

What would you use the 20mm f2.5 on? It is a movie camera lens, probably a 'C' mount. That will in no way cover a 35mm frame at infinity even if you could mount it close enough to the film plane.

It says right in that first and last file: Cinematographico so those are out for 35mm use.

Middle looks interesting, maybe a Jupiter-8 evolution that never got made in big numbers?

Mustafa, as long as you limit yourself to secondary and tertiary sources you're imagination will be restrained. If you want to dream about lenses from the former Soviet Union, go to http://www.lallement.com/pictures/files.htm and download the 1963 GOI and 1970 and ’71 Yakovlev catalogs. They're in Russian. http://www.photohistory.ru/index.php , also in Russian, has fewer lenses but a few that aren't in the GOI or Yakovlev catalogs. http://www.zenitcamera.com/catalog/lenseslist.html has fewer still but a few that aren't listed elsewhere. And ask on www.mflenses.com.

Most of the lenses designed by GOI are very hard to find outside of the former Soviet Union. Cultivate sources there.

Theres a camera shop in Chernobyl selling them for half price.

Not likely. The diagram is that of a double Gauss variant; the J-8 was a classic Sonnar - a direct clone of the 50/2 Zeiss lens designed by Ludwig Bertele in 1931. Bertele was also responsible for the fast Ernemann lenses, which were the ancestors of the Sonnars.
