Notes About Movie Recording

Notes About Saving Images or Movies
The indicator showing the number of exposures remaining or the indicator showing
the remaining recording time flashes while images or movies are being saved. Do
not open the battery-chamber/memory card slot cover or remove the
batteries or memory card while an indicator is flashing. Doing this could result in
loss of data, or in damage to the camera or the memory card.

Notes About Recorded Movies
There may be some degradation in image quality when digital zoom is used. When
switching from optical zoom to digital zoom while recording movies, the zoom
operation stops temporarily.
The sounds of zoom control operation, zoom, autofocus lens drive movement,
vibration reduction, and aperture operation when brightness changes may be
recorded.
Smear (A96) visible in the monitor with movie recording is recorded with movies.
Avoiding bright objects such as the sun, reflections of the sun, and electric lights is
recommended.
Depending on the distance to the subject or the amount of zoom applied, colored
stripes may appear on subjects with repeating patterns (fabrics, lattice windows,
etc.) during movie recording and playback. This occurs when the pattern in the
subject and the layout of the image sensor interfere with each other; it is not a
malfunction.

Notes About Autofocus for Movie Recording
Autofocus may not perform as expected (A42). Should this occur, try the following:
1. Set Autofocus mode in the movie menu to Single AF (default setting) before
starting movie recording.
2. Frame another subject (positioned at the same distance from the camera as the
intended subject) in the center of the frame, press the b (e movie-record)
button to start recording, and modify the composition.
