Subject: Re: [Leica] RF question from an SLR kind of guy

Since using a rangefinder, my DOF has become much shallower because the RF 
lenses I have are, for the most part, better than my Nikon SLR lenses were. 
I use the markings on the lens for some things, but I tend to shoot wide 
open or nearly so for most subjects. My preference is to remove the 
distractions in the background by throwing them into a sea of bokeh. When I 
do want some background in focus, then I go for the optimum aperture (which 
is usually f/8) and rely on hyperfocal settings.
