Your P&S has huge DOF which can work to your advantage. Simply pre-focus anywhere close to where you anticipate the action and wait for it to come to you...click! Also, set it to Continuous Shooting to get several frames. I do it all the time with super results.
Challenge accepted! I will try to get some pics with movement in...sports or something...see how it copes. Apparently the new tracking on the G12 is some of the best you can get in a compact...lets put it to the test.
