The Canon EOS 5D Mark IV is a powerful DSLR camera that boasts exceptional image quality, impressive low-light performance, and advanced autofocus capabilities. However, with great power comes great complexity, and many photographers struggle to master the autofocus system. In this article, we’ll delve into the world of autofocus and provide you with a comprehensive guide on how to focus your Canon EOS 5D Mark IV like a pro.
Understanding Autofocus Modes
Before we dive into the nitty-gritty of focusing, it’s essential to understand the different autofocus modes available on your Canon EOS 5D Mark IV. The camera features six autofocus modes, each designed to cater to specific shooting situations:
One-Shot AF (Single Shot AF)
In One-Shot AF mode, the camera focuses on a single point and locks onto it as long as you hold the shutter button halfway down. This mode is ideal for static subjects, such as portraits, landscapes, or still-life photography.
Ai Servo AF (Continuous AF)
Ai Servo AF mode is designed for tracking moving subjects. The camera continuously focuses on the subject as it moves, making it perfect for capturing action, sports, or wildlife photography.
Ai Focus AF
Ai Focus AF mode is a hybrid of One-Shot AF and Ai Servo AF modes. The camera starts in One-Shot AF mode and switches to Ai Servo AF mode if the subject begins to move.
Manual Focus (MF)
In Manual Focus mode, you take complete control of focusing using the lens’s focus ring. This mode is ideal for situations where autofocus may struggle, such as low-light environments or when using certain types of lenses.
AF- Area Selection Modes
The Canon EOS 5D Mark IV features three AF-area selection modes:
Single-Point AF ( Manual selection)
Allows you to manually select one of the 61 autofocus points to focus on.
Zone AF (Manual zone selection)
Divides the autofocus points into nine zones, enabling you to select a zone to focus on.
Large Zone AF (Manual zone selection with expansion)
Similar to Zone AF, but with the added flexibility of expanding the selected zone to include adjacent points.

What is Autofocus and How Does it Work?
Autofocus is a camera feature that allows the lens to automatically adjust its focus on a subject, ensuring that the image is sharp and clear. The Canon EOS 5D Mark IV has a sophisticated autofocus system that uses a combination of phase detection and contrast detection to focus on a subject.
In phase detection, the camera uses a dedicated sensor to detect the phase difference between light rays passing through the lens, allowing it to quickly and accurately determine the direction and amount of focus adjustment needed. Contrast detection, on the other hand, uses the camera’s image sensor to detect the contrast between different areas of the image and adjust the focus accordingly. The 5D Mark IV’s autofocus system can switch between these two methods depending on the lighting conditions and the type of subject being photographed.
What are the Different Autofocus Modes Available on the Canon EOS 5D Mark IV?
The Canon EOS 5D Mark IV offers several autofocus modes, including One-Shot AF, AI Servo AF, and AI Focus AF. One-Shot AF is best suited for stationary subjects, where the camera focuses on the subject and locks focus until the shutter button is pressed. AI Servo AF is ideal for tracking moving subjects, where the camera continuously focuses on the subject as it moves.
AI Focus AF is a hybrid mode that automatically switches between One-Shot AF and AI Servo AF depending on the subject’s movement. The camera also has a manual focus option, which allows the photographer to focus manually using the lens’s focus ring. Additionally, the 5D Mark IV has several autofocus area modes, including Single-point AF, Zone AF, and Large Zone AF, which allow the photographer to select the area of the frame where the camera should focus.
How Do I Choose the Right Autofocus Mode for My Subject?
Choosing the right autofocus mode depends on the type of subject you’re photographing and its movement. For stationary subjects, One-Shot AF is usually the best option. For moving subjects, AI Servo AF is ideal, especially if you’re tracking a fast-moving subject. For subjects that may suddenly move, such as animals or children, AI Focus AF can be a good choice.
It’s also important to consider the lighting conditions and the distance between the camera and the subject. In low-light conditions, you may need to use a slower shutter speed, which can make it more difficult to track moving subjects. In such cases, using a wider aperture and a faster lens can help improve the autofocus performance.
What is Back-button Focusing and How Does it Work?
Back-button focusing is a technique where the autofocus is activated using the AF-ON button on the back of the camera, rather than the shutter button. This allows the photographer to separate the autofocus function from the shutter release, giving them more control over the focusing process.
By assigning the autofocus function to the AF-ON button, the photographer can focus on a subject and then recompose the shot without the camera refocusing. This can be particularly useful in situations where the subject is moving or where the photographer needs to focus on a specific area of the frame.
How Do I Customize the Autofocus Settings on My Canon EOS 5D Mark IV?
The Canon EOS 5D Mark IV allows you to customize the autofocus settings to suit your specific needs. You can access the autofocus settings through the camera’s menu system, where you can adjust parameters such as the autofocus mode, autofocus area, and tracking sensitivity.
You can also use the camera’s custom functions to assign different autofocus settings to different buttons or modes. For example, you can assign the AF-ON button to activate the autofocus function, or set up the camera to use different autofocus modes depending on the type of subject you’re photographing.
What are Some Common Autofocus Problems and How Can I Troubleshoot Them?
Common autofocus problems include slow or inaccurate focusing, especially in low-light conditions or when photographing moving subjects. Other issues may include the camera focusing on the wrong subject or failing to track a moving subject.
To troubleshoot autofocus problems, check the camera settings and ensure that the autofocus mode is set correctly for the type of subject you’re photographing. Also, make sure that the lens is clean and free of smudges, and that the camera’s autofocus sensor is not blocked. In addition, you can try using a slower shutter speed or a wider aperture to improve the autofocus performance.
How Can I Use Autofocus to Improve My Photography Skills?
Autofocus can be a powerful tool for improving your photography skills, especially when combined with other camera features such as continuous shooting and tracking. By mastering the autofocus function, you can take sharper, more focused images of moving subjects, and capture fleeting moments with greater ease.
To take your photography skills to the next level, practice using the autofocus function in different shooting scenarios, such as sports, wildlife, or street photography. Experiment with different autofocus modes and settings, and learn how to adjust them to suit your specific needs. Additionally, practice panning and tracking subjects, and learn how to use the camera’s predictive autofocus function to anticipate and capture fast-moving action.
