Canon's EF 600mm f/4L IS II USM Telephoto Lens has all the features needed to make it the go-to super long telephoto lens for professional photographers and anyone who has the highest standards for the gear they use.

The light weight (8.64 lb) is always welcome in very large telephoto lenses. Using 3 IS (Image Stabilization) modes 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.

Dust and water sealing keeps the lens functioning even in less than ideal conditions, and a Power Focus mode allows smooth focus change while shooting video.
