Super-Tele Zooms


Super-size your telephoto reach with a monster zoom lens. Matthew Richards searches out the best buys for your Canon camera.

Sometimes a standard telephoto lens can simply come up short. A typical 70-300mm zoom can lack sufficient telescopic reach when you’re shooting anything from birds in the garden to animals in the wild, or from sporting events to air shows. For greater reach, you’ll need a longer lens with more pulling power.

Over the next few pages, we’ll compare all of the latest super-telephoto zoom lenses currently manufactured to fit Canon DSLRs. Sizes go from large to enormous, and there’s an even broader spread of prices. However, all of them stretch to a focal length of at least 400mm, and some go extra-long to as much as 600mm. They’re also all fully compatible with both full-frame and APS-C format camera bodies. The latter gives a 1.6x crop factor, further boosting the effective telephoto reach.

A perennial problem, when shooting at such long focal lengths, is camera-shake. It’s therefore no surprise that every current super-telephoto zoom lens on the market for Canon cameras has optical image stabilization built in. They also feature fast and whisper-quiet ring-type ultrasonic autofocus systems. Even so, when it comes to additional features and build quality, there are major differences between some of the lenses on test. Let’s take a closer look…
