ISO Warning in "Warning for bad settings"
Created originally on Bitbucket by cdcdent (Jeremy Rourke)
I like to keep my 5DM3 ready to "shoot from the hip" with setting to P and AWB and the ISO set to AUTO - That way my first shot can be taken (with some certainty of capturing a reasonable Histogram) by flipping the ON switch, then I can worry about fine tuning of the dial settings for second and subsequent shots. May I suggest you add an additional line to the "Warning for bad settings" with a setting for ISO - That extra line would be; other than Auto ISO
