Trusted by professionals, Canon's optical viewfinder autofocus technology provides the ability to capture the moment with ease and minimum lag time.
Watch the action and get the shot you want, with minimal lag between what you see in the viewfinder and the photo you get when you press the shutter button.
Compose the image you want and get accurate and fast autofocus, thanks to a wide area covered by multiple AF points.
Keep your subject in focus even if it’s moving thanks to the camera’s accurate and automatic tracking.
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.
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.
Simply point the camera and press the shutter halfway – even if you move the camera to reframe the image, the focus stays locked at the same distance, letting you compose how you like.
AI SERVO AF
The camera continually focuses on your subject so even if you or your subject move, images remain sharp.
The camera locks onto your chosen subject, similar to One-Shot AF, but switches to AI Servo mode to keep your subject in focus if it moves.
By analyzing the image for skin tones, Color Tracking AF, which is powered by the DIGIC Image Processor of many Canon cameras, is able to determine faces in the image and focus quickly on them. This helps you to compose the image you want, while keeping the emphasis on your friends and family.
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.
A single autofocus point, selectable by the photographer, is used to determine where to focus. Best for when image composition is paramount.
One of 9 user-selectable areas is used by the camera to determine what the subject is, and then where to focus. Best when composition of a moving subject is important.
Large Zone AF
One of 3 user-selectable areas is analyzed by the camera to determine where to focus. Best for beginners or when shooting fast subjects.
The camera finds and focuses on a subject based on analyzing all autofocus points. Best for quickly focusing on off-center subjects.
