Every so often, a new big superzoom telephoto lens grabs everyone’s attention. Usually it’s the likes of Sigma and Tamron duking it out, but now it’s Canon making headlines with the Canon RF 200-800mm F6.3-9 IS USM, a serious challenger to the super-telephoto zoom throne.
In the realm of full-frame super-telephoto zoom lenses, there’s the battlefield-ready, big, green and mean Sigma APO 200-500mm f/2.8 EX DG (at an eye-watering £15K) or the Sigma 60-600mm f/4.5-6.3 DG OS HSM Sport (a sensible £1699).
The Canon RF 200-800mm offers a (potentially) record-snatching 600mm difference in focal length from wide to telephoto, and manages to achieverival lenses with slightly less ambitious focal lengths.
