AE means AUTOMATIC exposure. IF you have to press a button every time you want to take a new picture that isnt AUTOMATIC, that is more like metered manual with the exception that it changes to the correct shutter speed for you ONCE and wont update if needed unless you MANUALLY intervene over and over again.

It's a different way of doing it than you're used to, but it certainly *is* aperture-priority AE. And as others have mentioned, it is faster than turning a control to adjust shutter speed in metered manual mode. No comment on "thinking mans mode" as I'm not a "thinking man." ERN
