I'm having some trouble with understanding the function of AEL/AFL, more so the AFL part. I have my OM-D set, so the the Fn1 button functions as AEL/AFL. When I press the button, I see that it displays the "AEL" icon on the screen, and I understand that to mean that now my exposure is locked, so until deactivated, all shots will be taken at the same exposure settings. That part seems easy enough, but now the AFL. I'm not sure how that comes into play. Can someone please explain this function, and under what conditions you would use them? Thanks in advance!
