You slowly rack focus down the line of hurdles at the international track meet. There — alongside the fourth hurdle — is the perfect spot to preset your focus and exposure. You'll be capturing the world's next major track phenomenon just as she extends and hits her full stride. Thanks to this remarkable Canon L-Series 200-400mm f/4 telephoto zoom with built-in 1.4X extender, you'll be able to fill the frame with nothing but her face — or compose it so you see her whole body gathering itself to break a record. Being that it's a long-range zoom lens with a constant aperture through the entire range, you'll have options.
It's a Canon L Series lens, so you know that the optics are among the best they make. One fluorite element combines with four ultra-low dispersion glass elements, among others, to bring home images that are tack-sharp and free of any color distortions from end to end. Three modes of image stabilization allow you up to four stops worth of slower shutter speeds, so you can bring home great shots even in challenging light. To top it off, the 9-bladed circular aperture throws background elements in a gorgeous buttery-smooth blur when the aperture is wide-open.
And if you're finding moments to capture on the fly, this lens has the tools to make your work better in those conditions as well. A fast, ultra-quiet autofocus system utilizes its internal high-speed CPU and optimized algorithms to find subjects and lock them in — almost before you can frame them up.
