Canon Patents Insane 40-800mm f/4.5-5.6 Lens for Full Frame Cameras

Here’s another one for the “probably never going to get made but WOW” file. A month and a half after Canon patented a massive 1000mm f/5.6 DO lens and two months after the crazy 28-560mm f/2.8-5.6 patent, the company is at it again. This time they’ve patented an EF 40-800mm f/4.5-5.6!

The patent, originally spotted by Egami, actually describes four optical formulas for four different 40-800mm internal zoom lenses—two for full frame, two for PowerShot superzooms. And while the idea of a wide-to-super telephoto lens might seem really cool, chances that Canon would attempt to actually build this behemoth for a full frame camera are slim to none.

Still, it’s fun to see a massive company like Canon playing around with crazy ideas. I think they call it “in-o-vay-shun” or something.
