OK. But I didn't consider it a match to my standards:

Fair enough. This is the best we have unfortunately.

There are other folks who think this patent and its inventor are related to the summilux. For example:,4/00_pag.htm

As you know, in my opinion this is the correct patent - despite not matching the production lens exactly.
