while fooling around on the leica digital forum I have found numerous inquiries about the best way to handle wide angle, and virtually all the responses indicate less than desirable results with the add on screwmounts. I have to confess, I have never spent anytime actually using the leica as a way to capture movies. To clunky, single focus option, lousy audio, etc...I'm sure I could get better, but not my cup of tea for now.
