Setting Movie Servo AF Cautions When [Movie Servo AF] is Set to [Enable] ooRecording Conditions that Make Focusing Difficult • A fast-moving subject approaching or moving away from the camera. • A subject moving at a close distance to the camera. • When shooting with a higher f/number. • Also see "Shooting Conditions that Make Focusing Difficult" on =197. ooSince the lens is driven continuously and the battery power is consumed, the possible movie recording time (=586) will be shortened. ooIf AF operations are performed or you control the camera or lens during movie recording, the camera's built-in microphone may also record mechanical sounds of the lens or sounds of camera/lens operations. In this case, using an external microphone may reduce these sounds. If the sounds are still distracting with an external microphone, it may be more effective to remove the external microphone from the camera and position it away from the camera and lens. ooMovie Servo AF will pause during zooming or magnified view. ooDuring movie recording, if a subject approaches or moves away or if the camera is moved vertically or horizontally (panning), the recorded movie image may momentarily expand or contract (change in image magnification). 281
