You will see a real-time change in the EVF/LCD as you change your EV values with this short-
cut. It also works while the Zebra Mode is engaged. You can fine-tune the Zebra alert just by
pressing the
When used in conjunction with the Curves "Auto DR" Mode you should never miss another
blown highlight or dropped shadow again.
One drawback: If using the up and down buttons during a half-press to see Zebra alerts while
changing the EV setting, it will toggle your "Disable Overrides" on and off if you have that
feature engaged as well. A small price to pay for the ability to have these amazing features. One
work-around, set the EV step-size to 1/2 what you normally would use, then the
"Disable Overrides" shortcut will always toggle back to the original ON (or OFF) on every 2nd
EV +/- press, effectively resetting it where you wanted it in the first place.
Note also: This change is not saved between camera power-downs. If you would always like to
start out with a small negative preset EV value to avoid blown highlights, then use Canon's own
EV compensation setting for your startup EV value. This Fast EV Switch will reflect that value
on startup.

When using the Fast EV shortcut feature you can adjust how much you want to change the
EV compensation with each UP or DOWN keypress. Step size is increments. A major
improvement over the adjustment levels and steps in the original firmware.
