Canon’s advanced Dual Pixel CMOS AF technology brings lightning fast speed and precise accuracy to Live View autofocus.
Canon’s high-speed Dual Pixel CMOS AF offers fast, precise autofocus in Live View mode by using each and every pixel for both AF detection and image capture. For example, it can cover 80% of the horizontal and vertical area of the actual sensor. This is possible because each pixel is actually two separate, but closely adjacent, light-sensitive photodiodes.
Incoming light is split, and each pixel has two light-sensitive areas to read the different wavelengths. Called “phase detection,” the difference between these wavelengths is used to calculate how much to adjust the lens to focus the image. Not only is this method fast, but it’s also highly accurate thanks to the sheer number of sensors used.
With quick autofocus thanks to Dual Pixel CMOS AF, Canon’s high-speed continuous shooting helps you capture multiple images per second while still maintaining sharp focus in Live View.
Every Canon camera equipped with Dual Pixel CMOS AF has fast, accurate autofocus. On the EOS 77D, EOS Rebel T7i and EOS Rebel SL2 cameras, it’s not just fast, but the fastest in the world when using Dual Pixel CMOS AF during Live View shooting. They can focus in an incredibly quick 0.03 sec.* – less than the blink of an eye.
Focus Racking lets you smoothly transition from one focus point to another, such as from the background to the foreground, adding a professional look to your videos. For that extra creative touch, you can customize the speed and sensitivity of the transition to match the style of your video. Choose anywhere between slow and artistic to fast and dramatic.
With the Touch AF LCD screen, focus racking can be performed easily with the touch of a finger.
With Subject Tracking, the camera identifies the main subject in your photo or video and keeps it in crisp focus, even if it moves.
Automatically detect and track faces in the image, even while moving, so the smiles of your subjects can stay in focus.
Canon’s years of tireless improvement of AF performance and image quality with cameras and lenses has set the standard among Hollywood cinematographers, professional photojournalists and videographers around the world.
