[Leica] Leica R8 Focusing screens in the Canon 5D

Dear Luggers,
While saving up enough money for a Leica digital back I am using a  
Canon 5D with an adapter to exercise my Leica R lenses. Today while  
fooling around with my recently purchased Brightscreen p235d focusing  
screen, I have discovered that Leica R 8 screens will fit (snugly)  
into the 5D - the tabs are all in the right places and the screen is  
the exact dimension of the Canon 5D screen. It is a tight enough fit  
that when you drop the screen holder down to release the screen - it  
will stay in place. don't panic - blow some air on it and it will  
dislodge. Trying my two R 8 screens (the standard with focusing  
rangefinder and micro prism) and #14345 (Micro prism circle) I have  
concluded that my 5D front focuses when manually focussed and that I  
just don't see it on the standard Canon screen when using the lens in  
auto focus mode. I will take the month old body back to Canon and see  
if I can get them to adjust it with my Canon EOS 50 f1.4 and the  
standard Canon screen. I am returning the p235d Brightscreen (the  
view finder is too busy for my taste with the diagonal rangefinder  
and the micro prism circle ) and exchanging it for a p232 (micro  
prism circle only). By the time I get it I hope to have had the  
camera adjusted.
