I have camera set to MS + ES, so that when the speed limits of the manual shutter are exceeded (eg wide aperture + bright daylight) the ES will be used. If it causes an issue (none so far) I will change back to MS only.
Have this actually happened though? My fastest lenses are f1.4 and admittedly we are rarely overburdened with sunshine here in the UK but I just don't seem to need more than my XT1 mechanical shutter can handle (1/4000). Maybe I'm not using wide apertures as much as I thought.
