Easily one of most anticipated Canon lenses in recent time. A lens that most Canon users have looked at Nikon users with envy. According to Andy Rouse it looks like the new Canon EF 200-400mm F4.0 L with the unique built-in 1.4x teleconverter takes the ball and knocks it out of the park. Extremely fast auto-focus being close to the Canon 300mm F2.8 L in speed, superb sharpness easily surpassing any zoom out there and gives the most expensive prime´s a run for their money.
For any Canon user it’s a game changer.
