Recording Movies Cautions for Movie Recording ooDo not point the camera toward an intense light source, such as the sun or an intense artificial light source. Doing so may damage the image sensor or the camera's internal components. ooIf you shoot something that has fine detail, moire or false colors may result. ooIf or is set and the ISO speed or aperture changes during movie recording, the white balance may also change. ooIf you record a movie under fluorescent or LED lighting, the movie image may flicker. ooIf you perform AF with a USM lens during movie recording in low light, horizontal banding noise may be recorded in the movie. The same type of noise may occur if you focus manually with certain lenses equipped with an electronic focusing ring. ooShooting a few test movies is recommended if you intend to perform zooming during movie recording. Zooming as you record movies may cause exposure changes or lens sounds to be recorded, an uneven audio level, or loss of focus. ooLarge aperture values may delay or prevent accurate focusing. ooDuring movie recording, if you perform AF, any of the following may occur: The focus is temporarily greatly thrown off, changes in movie brightness is recorded, the movie recording stops momentarily, and the mechanical sound of the lens is recorded. ooAvoid covering the built-in microphones (=240) with your fingers or other objects. oo"General Movie Recording Cautions" are on =291-=292. ooIf necessary, also read "General Notes on Still Photo Shooting" on =231-=234. 245
