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 battery 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
The optical zoom ratio cannot be changed once recording starts.
There may be some degradation in image quality when digital zoom is used.
The sounds of multi selector operation, autofocus lens drive movement, and aperture
operation when brightness changes may be recorded.
The following phenomena may be seen on the screen while recording movies. These
phenomena are saved in the recorded movies.
- Banding may occur in images under fluorescent, mercury-vapor, or sodium-vapor
lighting.
- Subjects that move quickly from one side of the frame to the other, such as a moving
train or car, may appear skewed.
- The entire movie image may be skewed when the camera is panned.
- Lighting or other bright areas may leave residual images when the camera is moved.
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 (A55). Should this occur, try the following:
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 then modify the composition.
