New optical designs for Canon mirrorless megazoom lenses has been spotted online, including a monster Canon RF 100-700mm. 

The pair of new formulas describe the Canon RF 100-600mm f/4.5-7.1 and Canon RF 100-700mm f/4.0-8.0 – which would seem to come from the same design ethos as the recently announced Canon RF 100-500mm f/4.5-7.1 L IS USM
