Both are set for variations of Manual with back button focus. U1, I use most often, especially for any form of flash photography. U2, has a different metering mode and uses auto-iso (for non-flash).
AF is set to the default 'release button' in all other modes so the wife, who doesn't do BBF, can also use the camera.
So you can toggle BBF on and off? Clever.
