A very old Imagon.
This used without additional diagragm with holes? Fixed/constant "soft effect" ?

This is one made by Kunstler who invented the Imagon. All used the disks, although they might have mounted differently then Rodenstock ones.
Rodenstock bought Kunstler a very long time ago.
Sorry, Kuhn invented the Imagon. Not Kunstler.
How many glass surfaces are there?

can not detect, have not in my hands now
Dr. Heinrich Kühn invented the concept of the Imagon. Dr. Franz Staeble was the lens designer. "Kunstler Portratobjektiv" would mean Art Portrait Lens.
While this lens clearly was made by Rodenstock, I had thought that very early Imagons might be written as Jmagon and as well 22 cm F 4 is an odd size. The image seems to have more elements that what we think of as an Imagon. I hope you get it and tell us about it.
Thank You , guys, for Your commen! If so happens for me to have this lens for test, i will tell You more about it!

Doesn't look much like an Imagon to me unless the front "lens" is a plain glass/filter?
Perhaps Rodenstock transferred the "Acquired trade name" to grace the Imagon product?

well...weirdly enough I just picked up one of those also. Appears to be basically an aperture and two elements. Does the photo help any?

anyone?
I have a very similar lens, same focus length and aperture. The difference is it has “soft focus lens” on the front rim.
I took the elements out, the front is single convex, the rear is two glass cemented.

I believe Rodenstock made an older (brass) version that was the inverse, the single element was in the rear. It was called 'hemi-anastigmat', I guess for 'half of an anastigmat'.
