Pre-flash is fired to pre-set the correct light
amount for the main subject.
Remarks:
FEL
only works on P, TV, AV, M & A-Dep mode.
Set the picture frame as you desire and release the shutter.
Remarks:
AE-L
only works on P, S, A & M mode.
When the back ground of the main subject is too bright, the camera’s
exposure reading system adjusts the flash light intensity for such back
ground condition and it results in the main subject being
under-exposed. Or in case the main subject is not placed in the center
of the viewfinder, the flash picture may result the aimed targeted
subject being under or over exposed.
You can lock the correct flash exposure for the targeted subject in
such a condition. This flash exposure pre-set remains locked in, even
if you change the aperture or zoom the lens in and out. This mode can
only be set on the camera.
