Canon files a lot of patents. In fact, 2015 marked their 11th straight year atop the list of Japan-based companies awarded US patents. The 4,134 total patents were enough to put Canon right behind IBM and Samsung to place third worldwide. That all being said, we wonder how many of these patents ever actually get the chance to see the light of day.

Here's one that we really hope does:


A patent showing the optical formula for an EF 1000mm f/5.6 IS DO

Publication No. 2016-102852
Published 2016.6.2
Filing date 2014.11.27

If this lens does, in fact, become a reality, it could prove to be one saliva-inducing piece of glass. While the focal length isn't a true 1000mm, 950mm comes pretty close and serves as a great replacement for their EF 800mm f/5.6L IS lens. Chances are, it'll be out of the price range for most of us (the EF 800mm currently clocks in at $12,999), but it may be affordable enough to try out via rental houses.

Here are some early tech specs:
