A brand new patent software from Canon has revealed the corporate is working to develop a trio of ultra-wide lenses for its RF mount mirrorless cameras.

First seen by Canon Information, the patent software particulars the optical designs for a 12mm F2.Eight lens, a 14mm F2.Eight lens and a 20mm F2.Eight lens. Usually, these patent purposes showcase a number of optical designs that don’t at all times make it to market, however Canon has each a 14mm F2.Eight and 20mm F2.Eight lens for its EF mount cameras, so it’d make sense to hold these two choices over to its mirrorless mount.

Beneath are illustrations and technical breakdown of every lens Canon has specified by Japan patent software 2021–047384.

As with all patent purposes, and even patents which have been granted for that matter, there’s no assure these will ever be developed additional. However two of the three designs are just like previous lenses Canon has launched, so it’s not out of the realm of prospects that we may see at the very least one in every of these designs sooner or later.
