"Lee - I use hyperfocal focusing all the time using the DOF scales on 
my Leica M lenses.  Are you saying that this won't be accurate with 
the M8 because of the cropping factor?"
   
  Tina-- Yes, that's right. I explained already in another post. With the 
smaller sensor, your enlargement factor will be larger, hence what's 
previously borderline sharp enough on 35 mm film will no longer be sharp 
enough on the M8.

  I think you should use the DOF markings for at least 1-2 stops wider, so 
if you want to shoot at F8, use the DOF markings for F4 or F5.6.
