Amin-

Very good summary of the issues. When you go back an forth between a compact and a Leica M camera, you realize that it's the automation that's getting in the way of the compacts responsiveness. No one is trying to capture the decisive moment while change exposure and getting the rangefinder images to overlap. The camera has been manually set to the right focus and metering and the trick is picking the moment and timing the shutter.

If you're coming from the SLR world though, you may miss the sophisticated, low light, continuous and predictive autofocus systems that are needed for the autofocus automation.
