D Recording Movies Banding or distortion may be visible in the monitor and in the final movie under fluorescent, mercury vapor, or sodium lamps or if the camera is panned horizontally or an object moves at high speed through frame. Bright light sources may leave after-images when the camera is panned. Jagged edges, false colors, moiré, and bright spots may also appear. When recording movies, avoid pointing the camera at the sun or other strong light sources. Failure to observe this precaution could result in damage to the camera's internal circuitry. In tripod mode, movies may be over- or under-exposed at some aperture settings. Before shooting, check the brightness of the scene in the monitor; if the picture is too bright or too dark, end live view and y adjust aperture as necessary. Note that depending on the brightness of the subject, changes to exposure may have no visible effect. Recording ends automatically if the lens is removed. Recording may end automatically before the maximum file size is reached when recording to memory cards with slow write speeds. When used in live view mode for extended periods, the camera's internal temperature may A 27s NORM AUTO [120m 00s] rise, resulting in image noise and unusual colors (the camera may also become noticeably warm, but this does not indicated a malfunction). To prevent damage to the camera's internal circuits, recording will end automatically before the camera overheats. A count-down display will appear in the monitor 30 s before shooting ends. At high ambient temperatures, this display may appear immediately when live view mode is selected. Matrix metering is used regardless of the metering method selected. The camera adjusts shutter speed and ISO sensitivity automatically. 61
