The corner performance normally suffers because the light comes from opposite diagonal, so corners will always be hit by non-vertical light.
Current generation of optics are big and complex to ensure corner sharpness.
But with curved sensors...
>Is there some advantage to this?Massively simplified lenses. Look up the various patents of lenses for curved sensors, many of them only consist of 4-8 elements.
Every lens can become as simple as the 50mm Double gauss design.
