A FYI, rather than a question. I use a Leica Rangefinder as a 'portable' camera and recently bought one of the Voigtlander 21mm lenses which came with the detac hable viewfinder. I also have a 65mm for LF and have found the viewfinder immens ely useful for 'sighting' a shot prior to getting all the gear out. They can be bought relatively cheaply on their own. Worth a look as they also do other commo n focal lengths.
Best regards
Dave
