A super telephoto zoom like the Canon RF 200-800mm f/6.3-9 IS USM lens is an incredibly versatile and popular optic. Now, a new Sigma patent hints that the third-party lens maker is working on an upgrade: a super telephoto zoom like Canon's but with a faster aperture and a broader zoom range for mirrorless cameras.
The super telephoto zoom market is highly competitive, with industry giants like Sony and Nikon battling along with top third-party manufacturers like Sigma. And that's great news for us photographers. Increased competition drives faster innovation, pushing manufacturers to deliver better optics at more attractive prices.
