EV Compensation for a and M modes
For example, if the EV compensation value is set to +1.5 for a
(Hyper-manual) and M (Flash X-sync speed) modes, an
underexposure of 1.5 EV is displayed on the EV bar. If you set the
exposure value so that the V is displayed at the center of the EV bar,
the image will be captured with the compensated value.
