  4. Select an option.

    • Enable

      • The camera focuses on the subject continuously even when you are not pressing the shutter button halfway.
      • To keep the focus at a specific position, or if you prefer not to record mechanical sounds from the lens, you can temporarily stop Movie Servo AF by tapping [Movie Servo AF paused] (1) in the lower left of the screen.

      • Movie Servo AF will resume if you return to movie recording after operations such as pressing the MENU or Playback button or changing the AF area.
    • Disable

      While you hold down the shutter button halfway, the camera will keep focusing on the subject continuously. Pressing the AF start button focuses only once.

Caution

  • Precautions when set to [Movie Servo AF: Enable]

  • Shooting conditions that make focusing difficult

  • Since the lens is driven continuously and the battery power is consumed, the possible movie recording time () will be shortened.
  • The camera's built-in microphone may also record mechanical sounds of the lens or sounds of camera/lens operations if AF operations are performed or the camera or lens is operated during movie recording. 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.
  • Movie Servo AF pauses during magnified view.
  • During movie recording, if a subject approaches or moves away or if the camera is moved vertically or horizontally (panning), the recorded image may momentarily expand or contract (change in image magnification).
