Reduce Camera Shake with Handheld Shooting

The lens offers 5.5 stop Image Stabilisation (IS) when used with the Canon EOS R or EOS R5 resulting in less shake when shooting with a large telephoto lens. The RF 400mm offers three IS modes based on the subject's movement and enables the user to experience stable handheld shooting.
