One of the problems that mirrorless cameras have is major defocus. This is when you attempt to focus on the subject with the lens completely out of focus. There's not enough contrast for the camera to determine just how far it needs to move the lens to reach focus on the target.
On DSLRs, Canon [. . . ]

I think it's pretty safe to say that Canon has all the ultra wide zoom lenses that they could possibly need, but we also have to keep in mind that once the dust settles and the lens start production, they are hard at work on the Mark II variant of the lens.
There's always the feeling I get when the amount of patent applications start to reach a tempo that perhaps it's a sign that Canon is about to do something. Mind you, Canon has trolled me in the past with this, so anything is possible.
About 3 years ago Canon showed off a prototype of a posture fit device that would recognize when you were slouching and generally having bad posture while sitting at your desk. It would then remind you to correct your posture.
In this patent application (2024-053967) Canon is looking to improve the ability of the cameras to calibrate the eye control focus with the photographer. The eye control focus is featured on older EOS film cameras and more notably, the Canon EOS R3.
In this patent application (2024-052498) Canon discusses replacing the gel filter at the back of a dual fisheye lens with something a little more robust and user-friendly. As you may know, the Canon RF 5.
In this patent application (2024-052503), Canon is looking at providing autofocus for dual lenses, such as the Canon RF5. 2mm f/2. 8L Dual Fisheye lens. The current dual fisheye lens is manual focus only, so this would be a step in the right direction.
In this patent application (2024-025100), Canon describes the optical formulas of some pretty impressive zoom lenses. In this patent, we see the impressive Canon RF 24-105 F2. 8L IS USM Z embodiment, and it's just as impressive as the lens is in real life.
