What To Know

  • Back button focus, however, separates these functions, allowing you to activate autofocus using a dedicated button on the back of your camera.
  • You can pre-focus on your subject by holding the back button, then press the shutter button to capture the image without interrupting the focus.
  • With back button focus, you can hold the focus button down, allowing the autofocus system to lock onto your subject before you press the shutter.

The Canon T7i is a fantastic camera for photographers of all levels, but one feature that can significantly enhance your shooting experience is back button focus. This technique allows you to control focus independently from the shutter button, giving you more control and flexibility during your shoots. If you’re wondering how to set back button focus on your Canon T7i, you’ve come to the right place. This comprehensive guide will walk you through the steps and explain the benefits of using this powerful feature.

Understanding Back Button Focus

Before diving into the settings, let’s understand what back button focus is and why it’s beneficial. Traditionally, pressing the shutter button on a DSLR triggers both autofocus and image capture. Back button focus, however, separates these functions, allowing you to activate autofocus using a dedicated button on the back of your camera. This provides several advantages:

  • Faster Focus: You can pre-focus on your subject by holding the back button, then press the shutter button to capture the image without interrupting the focus. This is particularly useful for fast-moving subjects or when you need precise focus control.
  • Enhanced Control: Back button focus gives you more control over the focus point selection. You can choose to use the autofocus system’s intelligent tracking or manually select specific points.
  • Reduced Camera Shake: Pressing the shutter button can introduce camera shake, especially in low-light situations. By separating focus and shutter release, back button focus minimizes this issue.
  • Improved Focus Accuracy: With back button focus, you can hold the focus button down, allowing the autofocus system to lock onto your subject before you press the shutter. This leads to more accurate focus and fewer missed shots.

Setting Up Back Button Focus on Your Canon T7i

Now that you understand the benefits, let’s get your Canon T7i set up for back button focus. Here’s a step-by-step guide:
1. Access the Custom Functions Menu: Press the Menu button on your camera.
2. Navigate to the Custom Functions: Use the navigation buttons to scroll to the “Custom Functions” tab, usually denoted by a wrench icon.
3. Select the Focus Control Option: Within the Custom Functions menu, find the option labeled “Focus Control.” This might be under the “Shooting” or “Custom” settings.
4. Choose the Back Button Focus Setting: You will see a list of options, including “Shutter Button,” “AF-On Button,” and “Both.” Select “AF-On Button” to activate back button focus. This will assign the autofocus function to the dedicated button on the back of your camera.
5. Confirm the Setting: Press the Set button to save the changes.

Selecting the Right Focus Mode for Back Button Focus

With back button focus enabled, you can choose from various autofocus modes to suit your shooting style. Here are some popular options:

  • One-Shot AF: This mode is ideal for stationary subjects. The camera focuses once when you press the back button and locks the focus until you release it.
  • AI Servo AF: This mode is perfect for moving subjects. The camera continuously tracks the subject and adjusts the focus as it moves.
  • AI Focus AF: This is a combination of One-Shot AF and AI Servo AF, automatically switching between the two modes depending on the subject’s movement.

Tips for Using Back Button Focus Effectively

  • Practice Makes Perfect: It takes some time to get used to back button focus, so practice using it in different situations.
  • Use the Focus Button for Precise Control: Don’t just tap the focus button. Hold it down to allow the autofocus system to lock onto your subject.
  • Adjust the Focus Point: Utilize the focus point selection system on your camera to choose the appropriate focus point for your subject.
  • Experiment with Different Focus Modes: Try the different autofocus modes and see which one works best for your shooting style.

Back Button Focus: A Game Changer for Your Photography

Once you get the hang of it, back button focus can become an indispensable tool in your photography arsenal. It gives you more control over focus, allowing you to capture sharper images and react quickly to changing situations. With practice, you’ll find yourself taking more compelling and technically sound photos than ever before.

Mastering the Art of Back Button Focus: A Final Word
