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 may cause the total movie shooting time or the
number of possible shots to decrease. 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 the external microphone IN terminal to anything other
than an external microphone.
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 the insufficient remaining capacity of
the card, the movie shooting remaining time (p.156) 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 the movie shooting, the movie shooting
might stop. If the still image recording quality has been set low, the movie
shooting might continue instead.
When movie shooting is set, certain Custom Function settings will be
disabled (p.221).
If there is a very bright light source in the picture, the bright area may
appear black on the LCD monitor. In movies, the bright areas will be
recorded in almost the same way you see it on the LCD monitor.
In low light, noise or irregular colors may appear in the image. In movies,
the bright areas will be recorded in almost the same way you see it on
the LCD monitor.
