I have recently been told that when you recompose your shot, even though you have locked the focusing function by holding the shutter button down, when you recompose your shot the automatic exposure metering is still active and adjusts to the new composition. This makes no sense to me. Why would one function (focusing) be locked while the other function (exposure metering) be active?? I could understand that you need to focus on an object, pressing the shutter button half way, and then turn the Auto Focus button on the lens to manual (basically deactivating auto focus), then recompose you shot, press the shutter button down again to activate the exposure metering, and then taking your shot working.
I also think you can go the other way and use the AE lock button. I think this process would be to focus where the final shot needs to be taken by pressing the shutter button halfway, press the AE lock button to lock the exposure metering function, then release the shutter button and focus on the object you want holding the shutter button halfway, recompose your shot and then finish pressing the shutter button.
Looking for some words of wisdom. And yes, I know I could go to back button focusing but that seems like a new world of pain that I haven't entered yet.
Thanks for the responses.

I think you understand the process you first mentioned - isn't that enough for you to practically know? The ideas you expressed may help me in understanding why BBFocus works better for me. Anyway, I think you are already overloaded with focusing and exposures!! LOL enjoy.
