Canon patents zoom lenses that get shorter as they get longer

by Leave a Comment

Well, this is a bit counterintuitive. Spotted by asobinet, Canon has patented a mechanism for a zoom lens mechanism that actually gets shorter as you increase the focal length. Yes, that’s right, the exact opposite to how zoom lenses normally work.

The patent was published on November 18th to provide zoom lenses with large apertures and small size with high optical performance. A number of lens examples are included in the patent, including a couple with ranges of approximately 28-70mm and 28-60mm with f/2.8 and f/4 maximum apertures respectively.

I’m a big fan of cheap lenses. I don’t care even care if they mostly suck. Sometimes, a really cheap terrible lens can offer you exactly the look you’re going for – and it can get you there much more quickly than trying to degrade your image manually in post. But in this case…

Tommy, Stephen and Mitchell at TMS Productions decided to order some cheap filmmaking gear from Wish to see how well it actually worked. They got a cheap “4K” action camera and a 420-800mm f/8.3-16 telephoto zoom lens. So, why does the thumbnail say 3200mm? well, they bought a couple of cheap 2x teleconverters, too.
