Live View - Live View with new AF modes and large 7.5-cm (3-in.) monitor

Live View gives you an intuitive, familiar way to photograph playful pets or children on the move. Just flip a switch and you're ready to go. When Live View is activated and new full-time-servo AF (AF-F) is selected, the camera keeps subjects in focus without having to press the shutter-release button - convenient for photos and movies. There is also new face-priority AF that locks focus on faces, even on people not directly facing the camera. Live View makes D3100 as easy to use as a compact camera.

AF Mode for Live View and Movie Shooting
- New autofocus (AF) modes help capture moving subjects

Three AF modes - single-servo AF (AF-S), full-time-servo AF (AF-F) and manual focus (MF) - are available when using Live View or shooting movies.
For movies, use AF-F with subject-tracking AF. These help maintain focus on a selected subject and work together to continuously track a subject as it moves through the frame, realizing camcorder-like focusing.

Full-time-servo AF (AF-F)

Autofocus automatically begins after Live View is activated, tracking the subject continuously without having to press the shutter-release button.

Note: When shooting movies, noise from the lens motor may be recorded.

Single-servo AF (AF-S)

Great for stationary subjects. Focus locks when the shutter-release button is pressed halfway.

Manual focus (MF)

Focus manually.

AF-area modes for live view and movies - Four modes to capture subject

When using Live View or shooting movies, choose from four AF-area modes depending on the subject: normal-area AF, wide-area AF, face-priority AF, and subject-tracking AF.

Normal-area AF

Offers pinpoint precision when focusing on a small area - ideal when using a tripod.

Wide-area AF

A good all-round choice for a variety of subjects, both moving and stationary. It is especially well-suited for handheld shooting.

Face-priority AF

The camera can recognize up to 35 faces at a time then focus on the face that is determined to be nearest. Even if people in the frame move, the camera continues tracking and focusing.

Subject-tracking AF

D3100 ‘memorizes' a subject then automatically tracks it even if it moves. Should the subject momentarily leave the frame, the camera starts tracking again once it re-enters. By using this with AF-F (full-time-servo AF) you can also maintain focus on the subject while tracking. This is a great way to photograph active children and pets.

Note: Autofocus operation is interrupted while the camera is tracking the subject.
