Shooting Movies
For movie shooting, the ISO speed cannot be expanded to L (equivalent
to ISO 50) or H3 (equivalent to ISO 409600).
When switching from still photo shooting to movie shooting, check the
ISO speed settings again before shooting movies.
During movie shooting, avoid changing the shutter speed or aperture.
Doing so may record the changes in the exposure or create more noise
at high ISO speeds.
When shooting a movie of a moving subject, a shutter speed of 1/25 sec.
to 1/125 sec. is recommended. The faster the shutter speed, the less
smooth the subject’s movement will look.
The minimum shutter speed for shooting movies at a high frame rate will
be 1/125 sec. for NTSC and 1/100 sec. for PAL.
If you change the shutter speed while shooting under fluorescent or LED
lighting, image flicker may be recorded.
In step 4, if you cannot set the shutter speed or aperture, set the power
switch to <
1
> and turn the <
6
> or <
5
> dial.
Under [
8
6: Custom Controls ], if [
s
: Expo comp (hold btn, turn
)] is set (p.454), you can set exposure compensation while ISO Auto
is set.
When ISO Auto is set, you can press the <
A
> button to lock the ISO
speed. After locking the ISO speed during movie shooting, you can
cancel it by pressing the <
S
> button. (ISO speed lock is maintained
until you press the <
S
> button.)
If you press the <
A
> button and recompose the shot, you can see the
exposure level difference on the exposure level indicator (p.305)
compared to when the <
A
> button was pressed.
By pressing the <
B
> button when the camera is ready to shoot, you
can display the histogram.
