Overview Using the three mode Optical Image Stabilization of the Canon 300mm f/2.8L EF IS II USM lens allows you to shoot at shutter speeds 4 stops slower, and the advanced third IS mode activates only when the shutter button is fully pressed, so you can pan with fast-moving subjects without the IS function interfering with composition and framing.
