The AE lock only works when you keep pressing the wake up button (on the LHS of the lens mount when the body facing you). It is an easy way for me to check the exposure reading when I move the camera around for composition, without flapping the AE lock lever. Also, sometime when I use the AE lock lever, I forgot to flap it back. It is a higher risk for me to ruin the rest of the roll.
