A look at the Canon RF 200-800mm f/6.3-9 IS USM MTF

Canon has announced the Canon RF 200-800mm f/6.3-9 IS USM, the first super telephoto zoom that reaches 800mm. Canon also kept the price to a surprisingly low $1900. In this article, as much as I’d love to compare the MTFs against other notables from the other camps, the methods used for MTFs for Sony, Nikon et all are all different and you should never really use them for comparison. So for this lens, I’m going to go the practical way and compare this lens to the Canon RF 100-500L + extender.
