Autofocus sensors use edges and lines in the image to determine where to focus the lens. Some images contain aspects that can confuse some autofocus systems. With Canon’s DIGIC Image Processors and cross-type AF sensors, the camera can quickly and precisely focus on your subject, even when there are patterns in the image that are traditionally difficult to focus on.

Cross-type AF Sensor

To determine where to focus a lens, an autofocus system analyzes the image, often using horizontal or vertical lines as a reference. This could be anything from stripes in a shirt to edges of letters in a sign. Some autofocus sensors only detect one direction and stumble when the image has lines in the other direction. Cross-type AF sensors can use lines in either direction, and can accurately determine focus regardless of what’s in the image.

By combining quick autofocus and fast image processing, Canon cameras can take multiple images in rapid succession. This lets you shoot action-filled scenes and capture the precise moment you want. Or if you’re photographing people, you’re able to get the exact expression that best captures the mood. This feature is often used by professional sports and portrait photographers.

If every photo had a subject in the exact center of the image, autofocus would be easy. Because artistry and reality dictate a more creative use of the frame, a larger number of autofocus points are necessary. With Canon AF Area Selections you can customize how these autofocus points are used by the camera to best determine where to focus.
