Canon Patent Application: Canon RF 14-20mm F2.0

When you purchase through links on our site, we may earn an affiliate commission. Here's how it works.

In this patent application (2024-071267) Canon shows off a pretty awesome embodiment of a fabled Canon RF 14-20mm F2.0. We were rumored to see such a lens, but with Canon's supply issues, your guess is as good as mine if it's coming soon.

That all being said this looks like a pretty complete patent application even detailing the zoom group movement from wide to far, no image stretching, and nothing but Canon lens design expertise on display here.
