The Canon RF 24-105mm F2.8 L IS USM Z lens covers more angles than most bright standard zooms, but its oversized ergonomics make it better for rolling video from a tripod than taking handheld photos.
The Sony FE 400mm F2.8 GM OSS is everything a high-end telephoto lens should be sharp, quick to focus, and with a bright aperture for use in tough light. Of course, like any other lens in its class, it doesn't come cheap.
