Canon is investing in their new EOS R system in a concrete and solid way. Here is a Canon patent application (2019-020679) for an RF 70-300mm F/4-5.6 IS lens. This lens is the EOS R version of a very common lens aimed at non professionals, for the consumer market.
Next week (2/14/19) Canon will announce the EOS RP, the company’s first entry level full frame mirrorless camera, and a lens like the RF 70-300mm F/4-5.6 IS is sure to hit the market soon (most patent application never do). I’m just not 100% sure it’s also image stabilised.
