Several months ago Canon filed a patent for the Canon RF 14-21mm f/1.4L USM super wide angle RF mount zoom lens. The latest rumor claims that this Canon RF 14-21mm f/1.4L USM lens is currently being tested by select photographers. The official announcement date and shipping date are still unknown at the time of writing.
This Canon RF 14-21mm f/1.4L lens will be another “world first” type of lenses from Canon just like the amazing RF 28-70mm f/2 L USM.
In addition, Canon is working on a “crazy” prime RF-mount lens, which is expected to come next year, but currently the focal length and aperture are still unknown.
