Worth Knowing
−Premium pricing at $2,999 USD, significantly higher than competitors and the non-Z RF 70-200mm f/2.8 at $2,500
−Iris ring click function limited to photo mode on most EOS R bodies (only works in video mode on R5 II, R1, R50V)
−Heavier and longer than the non-Z RF 70-200mm f/2.8 L IS USM when used for photography-only workflows
−Some reports of bokeh artifacts including onion rings and soap bubble effect in specular highlights, with slightly harsh backgrounds
