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
