It this true?

A few notes, Canon loves to overhype their cameras, but you really need to read the footnotes first, for example, only 5 of their RF lenses can support 20fps:

RF15-35mm F2.8 L IS USM

RF24-70mm F2.8 L IS USM

RF24-105mm F4 L IS USM

RF24-240mm F4-6.3 IS USM

RF28-70mm F2 L USM

(according to their own FAQ).

Also, the electronic shutter is not usable because of distortion and banding, again according to Canon themselves, so it's only good when the lighting is ideal and when the subject is not moving ... not seeing the point of 20fps for static subjects?

Also, the mechanical shutter doesn't always get you 12fps, the battery must have more than 60% of the charge for that, otherwise it drops to 9.2fps, and even to 6.8fps.

Considering how poor the battery is, you're unlikely to keep it at >60% most of the time, so you won't get 12fps either ... and suddenly the camera is not that quick anymore, isn't it?

Considering the huge list of EF lenses that are 12/20 fps compatible (post 3 in this thread:, this information seems pretty suspect. None of the primes, even?
