Auto-focus, all of our cameras today are auto-focus. So you need to have one that will focus on your subject. If your subjects are still, not moving, all cameras will do a great job. If you shoot pictures in low light, you need a more sensitive camera that will do a better job focusing in low light. If you're doing moving subjects like sports in action, you need to have a camera with what's called tracking auto-focus. That's generally found on the SLR type cameras, not on the pocket cameras.
