We’re told that Canon will definitely release an RF 24-70mm f/2.8L IS in 2019. We don’t think that is a big secret as Canon has mentioned there are a few f/2.8 zoom lenses coming next year. We also suspect a wide angle f/2.8L zoom is coming as well as an RF 70-200mm f/2.8L IS.
The same source says Canon will likely release an EF 24-70mm f/2.8L IS sometime in 2019, possibly as early as May 2019.
There were no details given as to when we could expect an RF 24-70mm f/2.8L IS, but suspect it’ll be in the 2nd half of next year.
