Coordinated Control IS
For decades, Canon has been making in-lens image stabilisation (IS) systems better and better. Many EF and RF lenses now have IS functions, which give photographers and videographers new ways to express themselves through their images. The EOS R5 was the first EOS camera to have an image stabilisation system built right into the body. Controlling both the in-lens IS and the camera's in-body IS together corrects camera shake blur to the same level as speeding up the shutter by up to 8 stops. When it first came out, this camera had the best IS* of any commercial camera. A gyro sensor or accelerometer is built into both the camera and the lens to make the IS work. Together with the live-view image from the camera, these sensors are used to find motion or blurring very accurately across the whole camera and lens. The image processor and the lens CPU then work quickly on the camera shake data to cut down on detection mistakes between the camera and the lens. This figures out the right correction ratio, and to get rid of camera shake blur, the camera and lens each make their own optimised corrections. Images that are stabilised in this way can be used for both still photos and movies. In yet another way, this shows how advanced Canon's technology is in the world of photography.
