Ever wonder how artificial intelligence can instantly correct an image? The focusing capability included in the newest cameras makes this possible.
A camera feature known as autofocus automatically focuses on a subject. This feature is present in most typical digital cameras. Your camera model affects the available autofocus methods. Depending on the location or subject you wish to capture, you might employ various strategies.
Modern autofocus systems even employ artificial intelligence, which studies image archives to choose the best subjects to concentrate on.

What is AI Focus?
The most automated autofocus mode is this one. Artificial Intelligence Focus is the full form of this mode. It gives the camera the option to select either One Shot Focus or AI Servo AF.
The majority of DSLR cameras have an autofocus feature called AI Focus AF. Depending on the sort of topic the camera detects, it enables the camera to decide whether the subject is stationary or moving and will choose either One-shot AF or AI Servo AF. In some shooting modes for the Basic Zone, this mode is automatically employed.
One-shot AF is used for still images most of the time. The images that have one major focus point get captured with the most clarity.
AI Focus AF is a combination between:
- One Shot AF (focus, shoot, focus again)
- and AI Servo AF (continuous motion focus)
How does it work?
AI Focus is made to automatically select the most appropriate autofocus method. It is based on the detected subject’s behavior, whether it’s stationary or in motion.
If the camera tried to focus each time you hit the shutter button, this would not be possible. So you won’t need to switch between One Shot and AI Servo by limiting the shutter button to just shooting the picture. You should set it to autofocus mode for easy accessibility.
What is AI Servo?
Canon refers to continuous focus as AI Servo AF, or Artificial Intelligence Servo Automatic Focusing. It’s perfect for focusing on moving objects because it maintains its focus continually.
Although it is not perfect, it does a good job of assisting you in capturing moving objects. If the object is moving too quickly, it can miss the mark and produce an unfocused image. It is undoubtedly one of the best tools available for recording moving images, despite its limitations.
AI Servo is the focusing setting you need for moving subjects, although it won’t always work well.
How does it work?
When you push the shutter button in AI Servo focusing mode, the camera locks onto your subject and follows their movements. Additionally, it keeps them concentrated by anticipating the subject’s actions. Even when the subject or the photographer is moving, the focus is always shifting to keep the topic sharp.
Some Canon cameras with AI Servo can also adjust the focus point across the viewfinder automatically to follow a moving subject:
- Ahead of the camera
- Avoiding the camera
- Moving from setting to the next
Difference between AI focus vs. AI servo
When you look through the viewfinder while setting your autofocus area mode, you’ll see the different autofocus point configurations displayed as you cycle through your options.
Subject
AI Focus AF assumes that your subject is mainly still. But One-Shot AF, it knows that it might move.
On the other hand, AI Servo knows the subject is constantly moving. Which makes AI Focus the best software to use. AI Servo is more responsive to subjects in motion as it preempts their actions.
Speed
If you want to compare the speed between both modes, you need to consider the subject that is meant to be photographed.
AI Servo is more reactive to moving subjects because it anticipates their movements. Since AI Focus considers the subject as being mainly still, it takes more time to react.
Accuracy
When using a shallow depth of field, you’ll want to ensure autofocus accuracy.
It’s not so easy to determine which one to use, though. The accuracy between AI Focus vs AI Servo depends again on the subject.
If it’s moving slightly, AI Focus will be more accurate because it’s not changing as much, so it’s more stable.
However, AI Servo will be more accurate when the subject is in constant motion. This is because it tracks the subject faster and can quickly change the autofocus point.
Focus point
Very often new photographers get autofocus modes confused with autofocus area modes. These are two separate focusing functions and you need to set both options:
- The AF mode tells the camera to focus continuously or once
- The AF area mode tells the camera where to focus
These options would help you decide which focus point you want to set. Setting an autofocus focus point will save a lot of time and would improve efficiency drastically.
Conclusion
The dynamic interaction between AI Focus vs. AI Servo autofocus modes in photography provides a wide range of opportunities for shooting both still and moving subjects. The more automatic of the two, AI Focus, uses artificial intelligence to determine if a subject is stationary or moving, effortlessly alternating between One-Shot AF and AI Servo AF. This makes it the best choice for a variety of shooting settings.
By continuously altering the focus to anticipate their activities, AI Servo, also known as Artificial Intelligence Servo Auto Focusing, excels at maintaining focus on constantly moving subjects. About relatively motionless subjects, AI Focus prioritizes steadiness and accuracy.
AI Servo thrives in the realm of high-speed, dynamic photography, offering photographers the agility needed to track and capture subjects in motion. The choice between these modes ultimately depends on the nature of the subject and the desired outcome, allowing photographers to harness the power of AI to elevate their art.
