Just picked up a Zeiss Contax IIIa w/50mm f2.0 lens. I had an old 40.5mm cap which works. Does it take the 40.5mm filter from B+W or any other manufacturer? Does the collapsible B+W rubber hood screw in and not cover the viewfinder? Or, is another shade preferable? I tried my Leica shade which clips on but does not hold.
