If you're looking to take more control over your camera’s autofocus system, you may have heard about Back Button Focus (BBF). This technique separates autofocus from the shutter button, giving you more flexibility in certain shooting situations. But is it right for you? Let’s break down what it is, why you might want to use it, and why you might not.
What is Back Button Focus?
By default, most cameras focus when you half-press the shutter button. Back Button Focus changes this by assigning autofocus to a button on the back of your camera (usually the AF-ON or AE-L/AF-L button). This means the shutter button only controls exposure and capturing the image, while focus is activated separately.
Why You Might Want to Use Back Button Focus
More Control Over Focus – BBF allows you to lock focus on a subject and recompose without worrying about the camera refocusing when you press the shutter.
Faster Shooting for Moving Subjects – With continuous autofocus (AF-C), you can track a moving subject by holding the back button, then release it when you want to maintain focus at a fixed distance.
Avoid Accidental Focus Changes – In tricky situations like low light or shooting through obstacles, separating focus from the shutter can prevent unwanted shifts in focus.
Great for Sports and Wildlife Photography – Since you can quickly switch between tracking a moving subject and locking focus, BBF is ideal for fast-paced shooting.
Why You Might NOT Want to Use Back Button Focus
Takes Time to Get Used To – If you’re used to half-pressing the shutter for focus, switching to BBF requires retraining your muscle memory.
Not Ideal for One-Handed Shooting – If you often shoot with one hand, reaching for the back button while composing can be awkward.
Not Always Needed for Static Subjects – If you mostly shoot landscapes, portraits, or still-life images, BBF might not provide a huge advantage over traditional autofocus.
Should You Try It?
If you frequently shoot action, wildlife, or portraits with recomposing, BBF can be a game-changer. However, if you’re comfortable with your current focus setup and don’t feel limited, it may not be necessary. The best way to find out? Give it a try and see if it improves your workflow!
