Everything’s too short for birds, lol

Canon is trying to convince photographers that their new RF600 and RF800 lenses are the answer to that age-old trope.  Are the lens's IS and AF and the R bodies high-ISO performance good enough to give quality results at f/11?  I'm not actively shopping, so haven't investigated.  The lenses are certainly lightweight and at attractive price points.

"This lens is ideal for bird, wildlife, outdoor sports, and aviation photography."
