Len,

Yes, I know there is a problem with the 5D, but I think the 20D is ok, but I 
will certainly check first.  Thanks for the tip on the focus confirm adapter 
supplier here in the US.  I may just get one for my 24 if it is needed.  I 
am going to pick up the one from Gandy pretty soon as it has been delivered 
to my P.O. Box.  I am somewhat surprised that Gandy does not sell the focus 
confirm adapters also.

Regards,
Gene
