If it's for rangefinders only, then I should have voted for "only manual." I hit 'vote' before it occurred to me to limit my answer to only rangefinders. But the answer that includes all my gear is probably 90% manual and 10% auto. I'm starting to practice zone focus, though. The only time I use auto is with the sole p&s digital I have because trying to manually focus with that little dial on the back is a major PITA.
