Keeping the Camera Cool

If live view is used continuously for extended periods, the camera's internal temperature will rise, causing noise (bright spots, randomly-spaced bright pixels, or fog) to appear in images. Use live view only when taking pictures. Note that live view does not end when menus are displayed; unless you intend to resume shooting immediately, exit live view before using the menus.

Image Artifacts

Flicker, banding, or distortion may be visible in the monitor and in the final movie under fluorescent, mercury vapor, or sodium lamps, when power aperture is in use, or if the camera is panned horizontally or an object moves at high speed through frame. Jagged edges, color fringing, moiré, and bright spots may also appear. Bright bands may appear in some areas of the frame with flashing signs and other intermittent light sources or if the subject is briefly illuminated by a strobe or other bright, momentary light source. Noise (randomly-spaced bright pixels, fog, or lines) and unexpected colors may be more noticeable if you zoom in on the view through the lens during live view.

The Flicker reduction option (see this section) in the movie shooting menu can be used to reduce flicker under fluorescent, mercury vapor, or sodium lamps. The desired results may not be obtained if the subject is very bright, in which case you should try a smaller aperture (higher f-number).

Ending Recording

If the maximum length is reached, the memory card fills, the battery runs low, the live view selector is rotated to , the lens is removed, or the camera overheats, filming will end automatically and all footage shot to that point will be saved. No movie will be recorded if the battery is removed during filming.

Unavailable Menu Options

Menu items that are grayed out can sometimes be accessed by changing camera settings.
