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!
