I don't have a long focal length OM lens of f/2.8 or faster. My most
used OM lens on the 5D is the 24/2.8 which probably has too much DOF to
focus precisely. I typically use hyperfocal methods with that lens
anyhow. Perhaps I should try the "S" screen with the 50mm lenses or,
especially, with the 85/2. Then I suppose I could see the difference.
