Patent: Canon EF 16-40mm f/4

We have been told that there was a possibility that the EF 16-35 f/2.8L II replacement could be wider, maybe the information was the EF 17-40 f/4L replacement instead.

By Canon Rumors | December 7, 2015

A patent for a zoom range smaller super telephoto has emerged. The optical formula is for an EF 200-600mm f/4.5-5.6 IS.
