Canon has created some very innovative and impressive lenses for the RF mount, with optics like the Canon RF 28-70mm f/2L USM pushing the boundaries of lens design and offering photographers new creative opportunities. It seems Canon is showing no signs of stopping, with several further patents for new mirrorless lenses emerging.
Canon News recently found a number of interesting lens patents for Canon’s RF mount, including a 35-135mm f/2.8, 30-110mm f/2.8, and 40-150mm f/2.8. Such a lens would surely be quite popular for a wide variety of genres. Of course, Canon would never bring three such similar lenses to the market (and we might not even see any of these), as it is likely they are testing different designs to find the best of the bunch. Nevertheless, it is certainly exciting to see an f/2.8 zoom lens that covers everything from wide angle focal lengths to medium telephoto, as this would surely be an incredibly versatile device that could handle a wide variety of situations with ease. It would likely be highly useful for video work as well, allowing filmmakers to cover many different scenes with a single lens. Let’s hope we see one of these eventually!
