I would be grateful if someone would explain how the focus lock button on the back of the G2 works. I don't understand the functional difference between this button and the shutter release button when depressed halfway. I had assumed that the focus lock button would enable you to lock focus and then take your finger off, without having to keep either the shutter release or the focus lock button depressed. But whenever I let go of the focus lock button the camera resets just the same as if I had half-depressed the shutter release to focu normally -- so what's the point? I assume there must be a good reason to have the focus lock button, but I haven't figured it out and don't find the manual helpful.
Thanks for any help.
