No, you won't get it in your next mirrorless Canon camera ;-) Canon press release:…
Canon RF 24-70mm f/2.8L IS and RF 15-35mm f/2.8L IS To be Released Within A Month
It seems that Canon is eventually releasing two of the “holy trinity” lenses they announced back in February 2019.
According to Nokishita the RF 24-70mm f/2.8L IS and RF 15-35mm f/2.8L IS lenses will be available for pre-order within a month.
The last “holy trinity” lens for the EOS R that’s still missing would be the RF 70-200mm f/2.8L IS, which we are pretty confident will also be released in 2019.
Prototypes or mockups of the upcoming lenses for the EOS R have been on display at CP+ 2019.
