I found a very cheap Domiron lens with fungus. Even with the fungus I'm very impressed with it. It has a bit of 3d pop and really good sharpness stopped down.
See what you think.

Your results wide open reminded me of the Helios-44, I see both lenses have similar optical construction Wink

Very nice Smile

Looks excellent!

This is a lens I'd love to own, but I'm not paying collector prices. Congrats on your find.

Thanks guys. Compared to the Helios 44 this lens has more "character" at f/2. I'm not sure about stopped down but I think the Domiron might have better edge sharpness.

Yes haha, a very beefed up Domiplan. The size was actually a surprise, the barrel is a lot bigger than the optics. Like a 1.2 lens.

I wonder how Meyer-Optik Görlitz could make so many special lenses.

According to http://zeissikonveb.de, the Domiron 2/50 was manufactured as a "high quality lens for the international market" - which was seen by Zeiss Jena as an unfriendly act: Soon, Meyer Görlitz was deprived of the high quality JENA Glass used for the Domiron, and had to stop its production.

Here's the glass used for the Domiron 2/50mm, taken from patent literature:

Very nice sample pictures. Does have the 3d pop up effect.

Nice bit of history there, thanks.

Yes that piece of history is interesting. So when they developed the Oreston 50mm f/1.8 were they still forced to use lower quality glass?

The Domiron 2/50mm had been built only for a few months during 1961.

The Oreston 1.8/50mm, presented 1965 in at the Leipzig fair, was made for the Praktica Nova. This SLR was the first Praktica SLR to be built in high numbers (up to 50 cameras per hour), and therefore lots of normal lenses were needed. Suddenly Meyer was part of the game again. I have never used or tested a Domiron nor an Oreston, but it seems that the first 1965 version of the Oreston 1.8/50mm was fairly well made (somehow inferior to the Zeiss Jena Pancolar 1.8/50mm). The later version of the Oreston 1.8/50mm (1969) was changed; two of the lenses now had a more pronounced curvature. This may indicate the use of glass with lower index (=cheaper), but i haven't found any detailed information about these lenses yet.

Later, the Meyer Oreston 1.8/50mm was re-named to "Pentacon Prakticar 1.8/50mm", while the Zeiss Jena Pancolar was renamed to "Zeiss Jena Prakticar 1.8/50mm". Slightly confusing, for sure.

I have an early Oreston 50 and a couple Pentacon 50s, and they are slightly different.

I'll have to examine them more closely now to see just how much different.

I've always thought the Oreston was better in a general sense, but I was never sure whether it was merely my own bias. The Oreston is certainly a much nicer looking lens.
