Movie Mode Cautions for Movie Recording zzDo 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. zzIf you shoot something that has fine detail, moire or false colors may result. zzIf [Q] or [Qw] is set and the ISO speed or aperture changes during movie recording, the white balance may also change. zzIf you record a movie under fluorescent or LED lighting, the movie image may flicker. zzIf 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. zzRecording 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. zzLarge aperture values may delay or prevent accurate focusing. zzDuring 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. zzAvoid covering the built-in microphones (=201) with your fingers or other objects. zzThe date/time/zone must be set to enable normal camera temperature control. Once the date/time/zone are set, temperature warnings can be displayed correctly. zzIf [Overheated! Shutting down.] is displayed, turn off the camera and wait at least 3 min. Note that the camera should be off for 9 min. or more if you will record a 4K movie up to 9 min. 59 sec. or a high frame rate movie up to 7 min. 29 sec. (Actual movie recording times may be shorter, depending on the recording environment and conditions of use.) zz"General Movie Recording Cautions" are on =242-=243. zzIf necessary, also read "General Still Photo Shooting Cautions" on =194- =195. 205
