is set and the ISO speed or aperture changes during movie
recording, the white balance may also change.
o
If you record a movie under fl uorescent or LED lighting, the movie image may
fl icker.
o
If 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.
o
Recording 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.
o
Large aperture values may delay or prevent accurate focusing.
o
When you press the shutter button halfway to perform AF during movie
recording, 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.
o
