How to Choose a Focus Mode for Live View Shooting on Your Nikon D5300

By Julie Adair King

By using the Focus mode setting for Live View shooting on your Nikon D5300, you specify whether you want the autofocus system to lock focus at the time you press the shutter button halfway or continue to adjust focus until you take the picture or throughout movie recording. Or you can tell the camera that you prefer to focus manually.

Here’s how things work at each of the Focus mode settings:

  • AF-S (single-servo autofocus): The camera locks focus when you press the shutter button halfway. This focus setting is one of the few that works the same during Live View shooting as it does during viewfinder photography. Generally speaking, AF-S works best for focusing on still subjects.

  • AF-F (full-time servo AF): This option is available for all exposure modes except for the Effects modes Color Sketch, Toy Camera, and Miniature.

    The main purpose of AF-F is to enable continuous focus adjustment throughout a movie recording. To use this option, keep your finger off the shutter button. Just switch the camera to the AF-F mode, wait for it to find its focus point, and then press the movie-record button to start recording.

    Focus is adjusted as needed if your subject moves through the frame or you pan the camera. If you decide to lock focus, press and hold the shutter button halfway down. As soon as you release the button, continuous autofocusing begins again.

    Unfortunately, there’s a downside that makes AF-F less than ideal. If you shoot a movie with sound recording enabled and use the internal microphone, the microphone may pick up the sound of the autofocus motor as it adjusts focus. So if pristine audio is your goal, use AF-S mode and lock focus before you begin recording, or abandon autofocus altogether and focus manually.

    As another option, you can attach an external microphone to the camera and place it far enough away that it doesn’t pick up the camera sounds.

    For still photography in AF-F mode, focus locks when you press the shutter button halfway, just as with AF-S mode. The only difference between the two modes is that AF-F mode finds a focusing target and keeps adjusting it until you press the shutter button halfway.

    You might find this option helpful when you’re not sure where a moving subject will be when you want to snap the picture: As your subject moves or you pan the camera to keep the subject in the frame, autofocus is adjusted so that when the moment comes to take the shot, you just press the shutter button halfway, pause, and take the picture.

  • MF (manual focus): Select this option to focus manually, by twisting the focusing ring on the lens.

    With the 18–140mm kit lens and some other Nikon AF-S lenses, moving the switch on the lens to the manual-focusing position automatically selects the MF Focus mode setting. For other lenses, you need to select the Focus mode setting yourself.

To change the setting, press the i button to activate the control strip. Then highlight the Focus mode setting and press OK to display the screen where you can select the option you want to use.
