i just had the 1.8 version dissasembled for cla and on the rear group there is a cemented pair that has some haze inside of it, the weird thing is that it is seated inside metal screwed caps front and rear. I´m not sure if they are cemented together or they are glued together (in this case i might try to open it i guess). Besides, the final image has the extreme right side softer than the left one up to f8, i will have to try other lenses to see if there is some issue with the adapter.

In case someone is still interested in Petri lenses: I wrote an article about the 1.8/55 (6 lens double Gauss Design) and particularly the 1.4/55 (7 lens design, very similar to the famous Pancolar 1.4/55) with bayonet mount: Petri 1.4/55 and 1.8/55. Much of the information I researched came from the Japanese Petri Wiki.
There have also been questions about their ancestor the famous Kuribayashi Orikkor 2/50, which is a marvel of a lens and for its time outstanding. It's quite a bit smaller than the newer lenses (but dense), more like a Canon or Leica rangefinder lens. It also has a 7 lens design, but is quite different from the more modern designs with 4 lenses in front of the diaphragm. Check it out at Lens-DB: Kuribayashi Orikkor 2/50. Its mount is M42.

Yes I know your article, very well written! I have both of them. They’re great bokeh lenses. The 55/1.8 is exceptional as a landscape lens as well (very sharp from corner to corner without having to stop down too much).

Thanks. Do you also have the tiny Kuribayashi Orikkor 2/50 (M42)? It's also a great lens, but its bokeh has lots of "character". In my opinion it's a lens worth having. Often it's quite expensive, but if you look for a Petri Penta, it might be attatched to it and much cheaper.

It is quite hard to search the Petri Wiki. I found the old brochures most informative (well, a few of them):

This is the site, where you can find the Brochures.

For instance (PDF):

Petri Catalogue containing lens scheme of the 1.8/55

Petri Catalogue containing lens scheme of the 1.4/55

Nope, don’t have that one. I’ll keep my eyes open.
