New Canon Patent: 17-40 f/2.8-4 Lens

Japanese site egami (Google translation) spotted a Canon patent for a 17-40 f/2.8-4 lens. She successor of the highly popular EF 17-40 f4L USM lens? Looks like. With the new 5D Mark III available in the near future it wouldn’t be strange if Canon decides to upgrade the EF 17-40 f4L USM lens. Surely a good lens for a full-frame camera, and, btw, the cheapest of Canon’s L lens.

 

More images from the patent and specification on egami’s site.
