In-lens IS (Optical Image Stabilizer)
Whether you are a professional or an amateur photographer, camera shake is a problem that you'll often have to deal with. Increasing the shutter speed is the most common way to fix camera shake. The minimum optimal speed is usually found to be 1/x seconds, where x is the focal distance in millimetres. Canon came up with a high-precision in-lens image stabilisation (Optical IS) system that fixes this issue and makes up for camera shake. Light from the subject is bent away from the optical axis when the shutter button is pressed with an unsteady hand on the camera lens. The picture is now blurry. Canon's Optical Image Stabilizer (IS) move the lens group so that it is parallel to the focal plane. The image will stay sharp and clear if the IS lens group moves in a plane perpendicular to the optical axis to match the amount of image shake. This is because the light rays that reach the imaging surface will stay steady.
Canon uses two oscillation gyros in the lens to pick up any tilt. The positioning of the Optical IS lens group is changed by a small but very responsive moving actuator. Once the IS lens group is in place, sensors that send feedback confirm it. The system puts the best IS lens array in the best spot for each lens. Even though the idea is simple, the image stabilisation that comes out of it is very accurate. This adjustment also keeps the picture in the viewfinder steady, which makes it easier to frame the subject and put the picture together.
One of the best things about Optical IS is that it lets you take accurate pictures by looking through the viewfinder. Canon wants to stay at the top of the performance rankings for high-performance cameras with interchangeable lenses. Canon's L-series lenses with Optical IS come in a wide range of types, from wide-angle to super telephoto. This gives professional photographers more shooting options than ever before.
