After Canon released the new RF 28-70mm f/2L USM lens for Canon full frame mirrorless cameras, there are rumors that Canon will release a “holy trinity” of RF mount f/2L zoom lenses. According to latest rumors, next f/2L zoom lens will be Canon RF 14-28mm f/2L USM lens. And the telephoto zoom f/2L lens will be RF 70-135mm f/2L USM lens.
Canon recently has filed two new RF lens patents in USA and Japan. Both lens patents are RF mount ultra-wide zoom lenses. The first one is RF 14-28mm f/2L USM lens, this lens will pair nicely with the RF 28-70mm f/2L USM lens. The second one is RF 10-24mm f/4L USM lens or RF 12-24mm f/4L USM lens, similar to EF 11-24mm f/4L USM lens.
