If you've got an extra 12-grand sitting around and you're not sure where to invest it, might I suggest the new Canon EF 200-400mm f/4L IS USM Extender 1.4X Lens? That name is a mouthful, and you may be wondering about the last bit of it. The first part is easy enough: Canon's got a new L-series 200-400mm telephoto zoom with a maximum aperture of f/4 and built in image stabilization. Sounds great. What's even better, of course, is the integrated 1.4X telextender. Just flip a switch and this 200-400mm zoom becomes a 280-560mm zoom, without ever removing the lens from the camera. Pretty cool. I'm guessing sports shooters are going to love this lens, flocking to it like... well, like sports photographers to a brand new super telephoto zoom with all the bells and whistles you could ask for. I'd really love to have that on, say, my 70-200mm zoom, turning it into essentially a 100-300mm with the push of a button. I wonder if this will become a de-facto accessory for long zooms? And I wonder about Power Focus mode, which debuted on earlier telephotos but isn't yet prevalent. Rotating a secondary focus ring utilizes the autofocus motor to make for super smooth focus pulling from one point to another—perfect for video. I'm also hopeful that maybe at some point in the future a similar technology may be incorporated into lenses that allows for power-assisted zooming too.
