Canon patents optical formula for an RF 200-500mm f/4L IS 1.4x

Hoping this means Canon will repeat what they did with the EF 200-400 and 400 DO II and have two lenses that get you to 500 f4, just with one being a compact, lightweight prime and the other being a big hefty (but extremely flexible) zoom. The integrated TC is really going to be the kicker here, if they don’t follow suit with what Nikon’s doing with their supertele’s that’s a huge mistake IMO. Not having to fumble around with caps, remove the body from the lens, or rebalance a gimbal would be incredible.
