Hello. Does anyone has any information or experiences about this lens? Is it the same as Pentacon 2.8/135, or the same as Contax Zeiss 2.8/135? Any optical formula? Performance?

And what about performance? Same as Pentacon? And the zeiss label? I think it could be better than pentacon. Not?
Pentacon optical formula, zeiss quality->better than common pentacon 2.8/135. Am I wrong?
Could it be better than sonnar 3.5/135?

This is a rebagged Pentacon as I said before, same.

Don't expect better quality or anything else. You can buy Sigma made lenses
labeled to Carl Zeiss Jena too and really not Zeiss quality.

It is a good lens, but like Attila said, it is a pentacon (meyer) design.
The Carl Zeiss Jena version is 135 / 3.5

Did you buy this lens? You will need to convert or buy an expensive adapter.

I once had a PB mount camera ("Jenaflex") and the 135mm lens seen in this this thread. I think the optics were (are) actually good, but both my 135 and others I've seen had a serious mechanical problem - the body of the lens became loose relative to the lens mounting flange. So loose that it seemed likely to fall apart ! I don't think it would be wise to spend a lot of money on an adapter for such a lens.

I didn't buy yet. I would DIY change the mount to m42 or Nikon. I have some mount parts home. So is it better than Sonnar 3.5/135?

No , not better. It is different. If you would like to use with M42 end take one with M42 mount instead.

This is one of my favorite lens , it has outstanding bokeh and perfectly soft at wide open for portraits.

On Nikon M42 version not reach infinity , but reach enough distance for portraits, I made my best portraits with this lens.

Very common lens as you know with M42 mount , so forget Praktica version.
