AE LOCK - Locking the exposure This function is suitable for situations when optimal exposure is difficult to achieve, such as when there is excessive contrast between the subject and the surroundings. For example, when the sky takes up much of the frame, shooting with automatic exposure sometimes results in a dark subject. Recompose your shot so that not much sky is in the frame. Then press x to lock the metered value (exposure) temporarily. Next, compose your shot again with the sky in the frame and take the picture. 5 Advanced shooting 1 When using the camera in the A/S/M mode, AE lock is not available in the M mode.
