According to latest rumors, Canon currently is working on another f/2 zoom RF mount lens for Canon full frame mirrorless cameras. The first f/2 zoom lens is RF 28-70mm f/2 USM lens, one of the best lenses in RF mount.
The focus range for this second RF mount lens is not available yet. Rumors said Canon is developing a “second holy trinity” of lenses for the RF mount, so this lens may be RF 16-28mm f/2L USM or RF 70-150mm f/2L USM. The current “holy trinity” is generally accepted to be the RF 15-35mm f/2.8L IS, RF 24-70mm f/2.8L IS and RF 70-200mm f/2.8L IS.
