Just purchased one and am real excited to get my mits on it!
I think its the only sub-16mm camera with a revolving mirror reflex viewfinder system, though correct me if I'm wrong- and its regular8 magazine loading!
Its supposed to have had an unparalleled viewfinder (there had to be a reason ;-) )
Had a set of 4 Zeiss primes and a zoom with a PL style breech bayonet mount
Weighs in at a hefty 2Kg though

Anyway, theres a German manual on the uploads ftp page so I guess someone has one or has knowledge of them. I'd love an English version if anyone has one? And if anyone has spare lenses/magazines drop me a line- mines coming with a 12.5mm f2 standard.
