In the lead up to NAB, Canon announced new parfocal full-frame Flex Zoom Lens Series with T2.4 aperture across the entire zoom range.
   

Specifically, the first two products in the line are the CN-E20-50mm and its telephoto companion the CN-E45-135mm. While designed for 4K shooting, the placement and internal lens types are designed to reduce color smudging and chromatic aberration with high performance from center provide sharp 8K imagery.

The lenses will be available with an interchangeable PL or EF mount and will transmit metada based upon the mount. PL mounts will deliver Cooke-I information while the EF mounts will transmit EF-mount data.

While Canon indicates the mounts could be user interchangeable, they were quick to point out that many users might prefer the change be done via your rental house or experienced technician.

The wide angle 20-50 is scheduled for early June 2022 shipping while the telephoto model should ship in early September. They are purchased mount-specific with the optional mount at extra charge.
