Understanding Autofocus on Canon Cameras

Autofocus is an essential feature in modern photography, allowing the camera to automatically adjust the lens to achieve optimal focus on a subject. Canon cameras, ranging from DSLRs to mirrorless systems, offer various autofocus modes and settings tailored to different shooting conditions and subject types.

The Science Behind Autofocus

The autofocus mechanism typically operates through two main systems: Phase Detection and Contrast Detection.

  • Phase Detection: Found mainly in DSLRs, this system uses dedicated sensors to measure the phase difference between light coming through the lens. It is fast and efficient, making it ideal for tracking moving subjects.

  • Contrast Detection: Commonly used in mirrorless cameras and when Live View is engaged on DSLRs, this method analyzes the contrast in the image. It tends to be slower than phase detection but can deliver precise focus when the subject is still.

Types of Autofocus Modes

Canon cameras provide various autofocus modes for different shooting scenarios. Understanding these modes will help you select the best option for your situation:

One-Shot AF

This mode is perfect for still subjects. When you press the shutter button halfway down, the camera focuses once, allowing you to take a clear shot of stationary objects.

AI Servo AF

Designed for moving subjects, this mode continuously adjusts focus as the subject moves. As long as you keep the shutter button pressed halfway, the camera will track the movement, ensuring your subject stays sharp in the frame.

AI Focus AF

This hybrid mode toggles between One-Shot and AI Servo. It automatically switches from focusing once (for still subjects) to continuous focusing (for moving subjects), providing versatility but requiring some attentiveness to camera feedback.
