I shoot landscapes; they give me more than a mere second!Zebra's or blinkies on the evf before shooting changed the whole exposure game for me.
I now essentially always shoot in manual- picking the aperture and shutterspeed needed.
I have my iso set up on one of the rear camera dials, and I can just dial in what iso I need- and it takes less than a second. You do have to pay attention.
But when a white egret pops up next to the heron I was shooting- the blinkies make me immediately aware I have to dial down iso before even my first shot.
It makes my life easier- of coarse I am getting older and dumber so I need all the help I can get.
