Canon to add 200-400mm f/4L to range
Canon has announced the development of a 200-400mm f/4L zoom to rival the hugely popular Nikon version, only this new lens features a built-in 1.4x teleconverter. With the converter applied (it has a locking mechanism from the picture below) the focal length alters to become a 280-560mm f/5.6 (we're assuming a one-stop light-loss). It's designed primarily for wildlife photographers (and especially the so-called safari crowd) but will also find favor with sports shooters. The small bulge on the side of barrel, with a lockable lever above, allows for the extender optics to be moved in and out of the optical train. The reasoning behind this? Well, Canon will have matched the converter to the lens, much like Nikon use to do with its speciailsed lenses; the 300mm f2.0 for one, but rather than supply it together (and run the risk of it being mismatched with the Mk II and Mk III converters) obviously decided the small penalty in weight and ergonomics was worth it. We shall see.
