I have just successfully registered and I'm very happy to be a part of the APUG family. My warmest greetings to all of you. So this is my very first posting on this forum and here it goes...
can anybody comment on the DALLMEYER Patent Portrait lenses and the "4A" in particular? So far I have learned that it is a modified Petzval design with SF mechanism, covers 10x8 and starts at f/4. But why is so little information on the web compared to the 2B, 3A and 3D? Is this a rare lens? Despite its designation as a portrait lens, is it also suitable for still life or outdoor photography, say, landscapes or nature closeups?
I look forward to all inputs, many thanks in advance!!!

Cheers, Carsten
