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."

all of those nice attributes still make these 2 sound like disposable lenses--just too good to be true
