One of the most requested super telephoto lenses for the RF system is a Canon RF 300mm f/2.8L IS USM. The Canon EF 300mm f/2.8L IS II USM has been discontinued for quite some time.
We have been told that Canon has prototypes out in the wild and that the lens is a ground-up redesign of the focal length.
The source claims that weight has been reduced by almost 40% and the length by as much as 30% over it's EF predecessor, though they didn't have the exact dimensions and weight to give us.
Weight savings in lenses is something Canon has been pouring a ton of R&D into, and this revelation shouldn't shock us.
We can reportedly expect to see the Canon RF 300mm f/2.8L IS USM some time in the first half of 2023.
Keep a close eye on the sidelines of the 2022 World Cup in Qatar in November.
