As a Nikon camera user, you’re likely familiar with the various buttons and controls that adorn your device. However, one button that often goes underutilized is the AF button. Located on the back of your camera, the AF button is a powerful tool that can help you take your photography to the next level. In this article, we’ll explore the ins and outs of the AF button, and provide you with the knowledge you need to use it effectively.
What Is The AF Button?
The AF button, short for Autofocus button, is a customizable button that allows you to control the autofocus function on your Nikon camera. By default, the AF button is set to activate the autofocus system, which helps your camera focus on a specific subject or area of the frame. However, the AF button can be customized to perform a variety of other functions, depending on your shooting needs.
Understanding Autofocus Modes
Before we dive into the specifics of the AF button, it’s essential to understand the different autofocus modes available on your Nikon camera. There are several autofocus modes to choose from, including:
- AF-S (Single Shot AF): This mode is ideal for stationary subjects, as it locks focus on a single point and remains fixed until the shutter is released.
- AF-C (Continuous AF): This mode is perfect for moving subjects, as it continuously adjusts focus to track the subject’s movement.
- AF-A (Auto AF): This mode automatically switches between AF-S and AF-C, depending on the subject’s movement.
- MF (Manual Focus): This mode allows you to manually focus the lens using the focus ring.

What Is The AF Button And How Does It Work?
The AF button, also known as the Autofocus button, is a feature found on many Nikon cameras that allows you to control the autofocus function separately from the shutter release button. By default, the AF button is set to activate the autofocus when pressed, allowing you to focus on a subject and then recompose the shot without losing focus.
When you press the AF button, the camera will focus on the subject using the selected autofocus mode. You can then release the button and recompose the shot, and the camera will maintain the focus on the subject. This feature is particularly useful for portrait and wildlife photography, where you need to focus on a specific subject and then adjust the composition of the shot.
How Do I Customize The AF Button On My Nikon Camera?
Customizing the AF button on your Nikon camera is a straightforward process that can be done through the camera’s menu system. To start, go to the camera’s menu and select the “Custom Setting Menu” option. From there, navigate to the “Controls” section and select the “Assign AE-L/AF-L button” option.
Once you’ve selected this option, you can choose from a variety of functions to assign to the AF button, including autofocus, metering, and bracketing. You can also customize the button to perform a specific function when pressed and held, or when pressed and released. This allows you to tailor the AF button to your specific shooting needs and preferences.
What Are The Different Autofocus Modes Available On Nikon Cameras?
Nikon cameras offer a range of autofocus modes that can be used in conjunction with the AF button. The most common modes include Single Shot AF (AF-S), Continuous AF (AF-C), and Auto AF (AF-A). Single Shot AF is best used for stationary subjects, while Continuous AF is better suited for moving subjects.
Auto AF, on the other hand, allows the camera to automatically switch between Single Shot AF and Continuous AF depending on the subject’s movement. Additionally, some Nikon cameras also offer advanced autofocus modes such as 3D Tracking and Group Area AF, which can be used to track complex subjects and scenes.
How Do I Use The AF Button For Back-button Focusing?
Back-button focusing is a technique that involves using the AF button to activate the autofocus, rather than the shutter release button. To use the AF button for back-button focusing, simply press and hold the AF button to activate the autofocus, and then release it to lock the focus.
Once you’ve locked the focus, you can recompose the shot and take the picture using the shutter release button. This technique allows you to separate the autofocus function from the shutter release, giving you more control over the camera and allowing you to focus on specific subjects without accidentally refocusing on something else.
Can I Use The AF Button With Other Camera Functions?
Yes, the AF button can be used in conjunction with other camera functions, such as metering and bracketing. For example, you can assign the AF button to activate the camera’s spot metering mode, allowing you to take precise meter readings from a specific area of the scene.
Additionally, you can also use the AF button to activate the camera’s bracketing mode, allowing you to take multiple shots at different exposure settings. This can be useful for capturing high-contrast scenes and creating HDR images.
Is The AF Button Available On All Nikon Cameras?
The AF button is available on most Nikon DSLR and mirrorless cameras, but the specific features and functions may vary depending on the camera model. Some entry-level cameras may not have a dedicated AF button, but may still offer autofocus control through the camera’s menu system.
In general, it’s best to check your camera’s manual or manufacturer’s website to see if the AF button is available on your specific camera model, and to learn more about its features and functions.
How Do I Get The Most Out Of The AF Button On My Nikon Camera?
To get the most out of the AF button on your Nikon camera, it’s essential to practice and experiment with different autofocus modes and techniques. Start by familiarizing yourself with the camera’s autofocus system and the different modes available.
Then, practice using the AF button in different shooting situations, such as portrait and wildlife photography. Experiment with different autofocus modes and techniques, such as back-button focusing and spot metering, to see what works best for you and your photography style.
