_1_ Notes About Saving Data
After taking pictures or recording movies, the number of exposures remaining or the remaining
recording time flashes while images or movies are being saved. Do not open the battery-
chamber/memorycardslotcover. Image and movie data could be lost and the camera or memory
card could be damaged,
_1_ Notes About Movie Recording
• Memory cards with an SD Speed Class rating of 6 or faster are recommended when recording
movies (_),'-20). Movie recording may stop unexpectedly when memory cards with a lower Speed
Class rating are used.
• image quality degrades when digital zoom is used. When recording ends, digital zoom turns off.
• The sounds of zoom control operation, zoom, autofocus lens drive movement, vibration
reduction, and aperture operation when brightness changes may be recorded.
• The following phenomena may be seen in the monitor 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 amou nt of zoom applied, subjects with repeating
patterns (fabrics, lattice windows, etc.) may have colored stripes (interference patterns, moire, etc.)
in them during movie recording and playback. This occurs when the pattern in the sub]oct and the
layout of the image sensor interfere with each other; it is not a malfunction.
_1_ Camera Temperature
• The ca mera may become warm when recording movies for an extended period of time or when
the camera is used in a hot area.
• If the inside of the camera becomes too hot when recording
movies, the camera may automatically stop recording after 10
seconds in order to prevent damage to the camera.
The amount of time remaining until the camera stops recording
(_10 s) is dispbyed.
When the camera stops recording, it turns itself off.
Leave the camera off u ntil the inside of the camera has cooled,
