Canon Zoom Telephoto EF 70-200mm f/2.8 IS EF-USM is the lens that ties with the Canon 16-35mm f/2.8. This is a great zoom lens for events taking place further away such as those on a stage or when you are in the audience and away from the action. The addition of the IS (image stabilization) minimizes the effects of camera shake, allowing handheld shooting at up to FOUR shutter speeds slower than what otherwise would be possible. This allows for a higher percentage of sharper images (without noticeable blurriness). This lens is tied for first place.
