Notes on Movie Shooting
Recording and Image Quality
If the attached lens has an Image Stabilizer, the Image Stabilizer will
operate at all times even if you do not press the shutter button halfway.
The Image Stabilizer will thereby consume battery power and may
shorten the total movie shooting time or decrease the number of possible
shots. If you use a tripod or if the Image Stabilizer is not necessary, you
should set the IS switch to <2>.
The camera’s built-in microphone will also pick up camera operation
noise. If you use a commercially-available external microphone, you can
prevent (or reduce) these noises from being recorded.
Do not connect anything other than an external microphone to the
camera’s external microphone IN terminal.
Autofocusing during movie shooting is not recommended since it might
momentarily throw the focus way off or change the exposure. Even if the
AF mode has been set to [Quick mode], it will switch to the Live mode
during movie shooting.
If movie shooting is not possible due to insufficient remaining capacity of
the card, the movie recording size and movie shooting remaining time
(p.176) will be displayed in red.
If you use a card having a slow writing speed, a five-level
indicator might appear on the right of the screen during
movie shooting. It indicates how much data has not yet been
written to the card (remaining capacity of the internal buffer
memory). The slower the card, the faster the indicator will
climb upward. If the indicator becomes full, movie shooting
will stop automatically.
If the card has a fast writing speed, the indicator will either
not appear or the level (if displayed) will hardly go upward.
First, shoot a few test movies to see if the card can write fast enough.
If you take still photos during movie shooting, the movie shooting might
stop. Setting a low image-recording quality for still images might resolve
this problem.
