An intriguing new patent from Canon shows off the optical formula for a non-fisheye EF 10mm f/2.8 lens.

Filed back in November of 2013, Patent Publication No. 2015–102620 (translated) shows off what could very well become the widest non-fisheye lens Canon has ever produced. From the illustration, it appears the lens will consist of 15 elements in 7 groups.

As noted by Canon Rumors, this patent could simply be part of an optical formula used to develop Canon’s EF 11–24mm f/4 lens. However, there’s the possibility it could also be used for a super-wide-angle prime in the future, a potential successor to Canon’s EF 14mm f/2.8 II lens.

As always, we’ll be sure to keep our eyes peeled for any other patents that display what Canon might be up to.
