Canon’s plans for exotic RF-mount lenses continues, with new designs for ultra-fast ultra wide-angle optics.
As a result the company filed patents for Canon RF 18mm f/1.0, Canon RF 18mm f/1.2 and Canon RF 25mm f/1.2 optics. Both lenses are not in Canon’s RF lens roadmap.
The Canon RF 18mm f/1.0 would be the company’s most extreme ultra-fast, ultra-wide lens. Check out the patent details below.
