Manual Exposure Shooting
During movie shooting, you can lock the exposure (AE lock) by pressing
the <A> button (p.115). After applying AE lock during movie shooting,
you can cancel it by pressing the <S> button.
If you set the power switch to <J> and turn the <5> dial, you can set
the exposure compensation.
The ISO speed will be set automatically within ISO 100-12800. If the
[Highest ISO speed] is set to [H1], [H2] or [H3] in [8C.Fn I -3: Set ISO
speed range] (p.208), the ISO speed will be set automatically within the
expanded range up to the upper limit. However, setting the [Lowest ISO
speed] to [L] will not expand the ISO speed range to the lower limit. Also,
even if the ISO speed range is set to a narrower range than the default,
the narrower range will not take effect.
Pressing the shutter button halfway displays the ISO speed, shutter
speed, and aperture at the screen bottom. This is the exposure setting
for taking a still photo (p.148). The exposure setting for movie shooting is
not displayed. Note that the exposure setting for movie shooting may
differ from that for still shooting.
