[Leica] Intro and question.

Bill,

Welcome to the LUG family.  This may have been already answered, as i am a 
bit late in seeing this, but here is a suggestion.  Do not use the live view 
to judge focus, you must use the eyepiece and focus screen for best focus. 
If you still do not get accurate focus, send the camera in to Canon to be 
adjusted.

Cheers,
Gene
