Canon 200-400mm f4L 1.4X lens for the birds
Even relatively bold birds such as this blackbird are small and twitchy, so photographers will need every bit of focal length and aperture. The Canon EF 200-400mm f/4L IS USM Extender 1.4X, at 8.3 pounds, isn't easy to move quickly to track fast-moving birds, but its 560mm f5.6 option, image stabilization, and sharpness are big assets for wildlife photography.
