Re: [Leica] Focusing with aging eyes

Mark,
Sorry, I should have mentionned that the one who scare the h*** out of me is the
guy who wears four types of prescriptions on the same side of the frame.  I can
just imagine this guy trying to make up his mind if 2 obstacles happen to show up
in front of his car...one at 5 feet and one at 20 feet and he's driving at 30mph.
Where is he going to focus then! :-)  Translating that in photo terms...I hope for
him that he is not photographing a basketball game with a rangefinder!
