Patent: Canon EF 10mm F2.8L USM lens

Canon has just filed a new patent of EF 10mm F2.8L USM lens. This is an ultra-wide angle prime lens for Canon full frame DSLR cameras.

EF 14mm F2.8L II USM lens

The Current Canon EF 14mm F2.8L II USM lens

Once released, Canon EF 10mm F2.8L USM lens will replace the current EF 14mm F2.8L II USM lens. We are very much surprised why this new Canon patent is not for a fisheye lens?
