Hi all, COntax IIA / IIIA has a higher 1/1250 shutter speed. Metal curtain shutter bind. better chrome and focusing adjustment. Sharper lens like SONNAR 50 , Bigon and Planar. But why are they still cheap than the Leica IIIF/IIIG or M2, M3 ??? Where's the value in contax? I happen to have a Contax IIIA color dial in Minty condition !!!
