Over the last few years, I've spend a fair amount of time at shows big and small all over the country and one moan I've had has been from Canon users complaining about the fact they've never had a decent usable wide lens. You've either had to go extreme to the 8-15mm f/4 L Fisheye or settle with the good old 16-35mm f/2.8 L or the newer 16-35mm f/4 IS L lenses. Problem is the Fisheye distorts the image and the 16-35mm isn't wide enough! What they've wanted is something akin to Nikon's brilliant 14-24mm f/2.8 ED lens. Well wait no more!!
Launched at the same time as the new 5DS twins, Canon clearly thinking that this lens will be an ideal partner, it is apparently the world's widest angle rectilinear zoom lens. What does rectilinear mean? Basically no distortion - straight lines appear as straight lines. If you try shooting at 11mm on an 8-15mm f/4 L Fisheye, very simply straight lines won't appear totally straight. I can see this lens being popular with motion shooters in particular - being able to offer 18-24mm equivalent on Super 35mm sensors will be very useful indeed.
The lens is naturally weather sealed which is probably a good thing if it's aimed at shooting outdoors. It features three aspherical lenses including a ground aspherical element, which Canon say maximises image quality and delivers minimal levels of distortion.
