[CW3] Canon EF 16-35mm f/2.8 Mark III in the works? Canon patent for 16-35mm f/2.8 lens spotted

16-35mm

embodiment: 16-35mm f/2.8

Last week I got a rumor I didn’t take seriously. The rumor suggested that Canon is working on a new version of the highly popular EF 16-35mm f/2.8L II USM lens. Well. I think I was wrong in not trusting the source. The EF 16-35mm f/2.8L II USM was released in 2007, so a replacement is not out of the realm of possibilities. Given the patent, I rate the rumour CW3.

Egami (translated) spotted a patent that appears to support the rumour of a EF 16-35mm f/2.8 Mark III lens.
