While their mirrorless bodies have received mixed responses, no one can accuse Canon of playing it safe when it comes to mirrorless lenses, and they're showing no signs of stopping, as patent documents have emerged showing a positively ludicrous lens design.
Canon Rumors is reporting that Canon recently filed a patent for a 50-80mm f/1.1 (no, that's not a typo) zoom lens for their mirrorless full frame mount. Of course, f/1.1 is a ridiculously wide maximum aperture for a prime lens, and it's entirely unheard of in a zoom lens. In fact, the widest full frame zoom lenses are the Sigma 24-35mm f/2 and the Canon RF 28-70mm f/2L; f/1.1 is approximately 1.72 stops faster than those. If the optical quality is there, photographers will essentially get a highly versatile portrait lens that offers both the classic headshot focal length and the half-body focal length.
Now, one has to remember, of course, that a patent is not the same as a product, and we see plenty of patents that never come to market. Nonetheless, Canon has shown that they can push the boundaries of design with the RF mount, and it's quite exciting to see that they're not slowing down.
