Subject: [Leica] IMG: More hairy(spiky) legs - Crab Spider revisited

I try not to stop down all the way unless I absolutely need the maximum
depth of field and can stand to deal with some of the defects. If my lens
goes down to f32 I'll try to shoot at least at f22 if not 16 if I want deep
focus.  My experience with most lenses is they are ok if they are opened up
one or two from the smallest f stop.
People on this list have said bizarre stuff like don't shoot at f8.
