I've set the f100 so the AF-L button just starts the AF and leaves it alone otherwise. The AE-L button locks the exposure on first tap, unlocks on second. They're all custom settings. And the shutter button just turns on the meter. This way I can point the central focus blot at what I want in focus, tap the AF-L button, re-frame the shot and press the shutter. If I need to fiddle the exposure, re-frame and tap the AE-L button, then re-frame again and shoot: focus will still be where I left it. I don't shoot action with that camera so this works real well.
