Part of the reason for needing this is that on the M8/M8x, there is no fast way to adjust the ISO, so if you were at 320 or 640 you can still get the shot if you are tracking something in and out of bright and dim lighting, where adjusting ISO is buried in menus. Something they did fix in the M9.
But, on M8.2, there is auto ISO, and EV can be adjusted +/- 3 stops with turn of rear wheel and slight pressure on shutter.
