IOR bucuresti - Unknown lenses

[Tefolium]

Hello everyone.

I am interested in former socialist countries' lenses.
I read an interview with the vice director Ion Gordu ( 扬·格尔杜 in Chinese, homophonic translation) about IOR on magazine Romania 1980.9. p9-11
He said that IOR had cooperated with Pentacon and Carl Zeiss Jena about optical instruments and cooperated with Leitz and Carl Zeiss AG about duplicator and projector lens in the last 15 years.
Here is a picture between p10-11.



Some of them are SLR lenses.
The bigger SLR lenses look like Pentacon 200/4, while the smaller I can not differ.
Can anyone differ them?

I've seen a few of these Romanian lenses on ebay in the past. They seem to be quite rare. They're very cool looking though.

Towards the fall of Pentacon (late 80's) they aimted to cut production cost and introduce accessible zoom lenses. So they transferred the cheapest stuff like the Orestor-based 50/1.8 and 50/2.4 to IOR and rebranded various cheap Samyang and Sigma zooms as Practicars.

So it's possible that many of those late Prakticar lenses were actually made by IOR.

I can't help you with the SLR lenses, but most probably they were not branded IOR. They made some RF cameras, too, with simple triplet lenses. Not bed lenses but nothing special. They never made a SLR camera, as far as I know.

I have some projection and enlarger lenses made by and branded IOR. They are quite rare this days. Some of them are quite good, at the same level with Meopta Meostigmat lenses. The IOR 50mm/f1 is, in fact, identical with the 50/f1 Meostigmat. I had both and disassembled them in order to adapt them to the E-mount.
I recall testing a tiny old 75mm/f4 IOR enlarger lens that proved to be very good but with reduced contrast.
The Meostigmat-like lenses are the silver ones in your photo. The smaller lense on the left-front are cine projection lenses. I still have the 50mm, 65mm and 75mm of that series.
