Hi Bob, That is a good theory.
I use eight double A rechargeable batteries in the S2 and always charge a complete set to be fresh in the camera when starting on a session. Of course I have battery back ups also charged. I let the batteries get low in the camera twice in the past year and all sorts of strange things started happening that I never would have suspected was a battery problem. For example, in the studio I use RC to trip the studio lights and they started misfiring. If I am doing a portrait in the studio or on location and the subject is fairly static, I do not use the shutter release to auto focus. I transfer that function to a button on back of the camera, it seems to help with any shutter lag due to the camera checking focus. Now the camera will fire whether in focus or not. I am using the camera's electronics to focus, but it is a my decision as when to focus, not the cameras. You have to set it to continuous to make it work with that setting. Of course you have to get used to doing it that way or you can really have the subject out of focus.
