Every so often, a new big superzoom telephoto lens pops up to grab everyone's attention. Mostly it’s third-party lens makers like Sigma and Tamron, duking it out over different stratospheric focal lengths or huge apertures. It seemed like Canon was content to focus on sensible quality and let other companies make the headlines. But no longer! The Canon RF 200-800mm f/6.3-9 IS USM has arrived on the scene as a serious challenger to the superzoom throne.
