Laack were a small lens maker in Rathenow, East Gemany and they made some interesting lenses.
I know the Dialytar and Dialytar T lenses.
Now I want to find information about the Dialytar Wideangle 90mm f/8.7
The only I found was mentined in "Das Auge meiner Kamera" (the eye of my camera) by Dr. Naumann from 1937.
He wrote that the lens has an angle of view of 100° and were made in foci between 75-250mm.
This means that the lens should cover 13x18cm (5x7") when stopped down but I never try it and before I start with it IŽam asking for experiencies someone has made with one of this lenses.
Is the design like the Meyer Wideangle Aristostigmat oder different? Is it fully symmetric?
Some of this lenses were rebrandet by the "Kullenberg, Essen" company.
It will be great when someone has information about this company as well.
