It would be nice if the RAW/Fx button could be programmed for AE-L.
once you assign the rear button for AF-L, what is the function of the half click?
if it's left redundant, then to fully decouple AF-L and AE-L is it possible to assign the function of Auto Exposure Lock to it??
if such a feature isnt present then could a firmware update do it, & preferable make the function of half press customizable from menu.
