Just like Sony also Canon now patented its first lenses made for Full Frame curved sensor cameras
Sony had already patented this idea years ago (SAR article here). And Canon is now following: They just patented their first lens designs made for a hypothetical future Full Frame curved sensor system.
A curved sensor would allow for a more compact design as you would not have to add a lot of glass to correct for corner issues. No more corner sharpness issues! The trade off is that of course it’s way more expensive to make such curves shaped sensors. So I have no clue when this idea will make it into a real production camera.
