These Might Be The Upcoming Canon RF 800mm f/5.6L IS And RF 1200mm f/8L IS Lense
We expect Canon to announce new gear on February 24, 2022. Two new telephoto lenses might be part of the announcement.
On top you can see a small image with the two lenses we now know Canon will announce on 2/24: the Canon RF 800mm f/5.6L IS and RF 1200mm f/8L IS. The image on top, which showed up on Chinese social media after it was leaked by mistake by Canon, even states the date (2/24).
Will there other gear that gets announced on 2/24? Likely. Stay tuned.
