Hey Trevor--I probably should have clarified what I wrote -- I was referring to the ef version of the 100-400. I have no doubt the RF 100-400 would be excellent.
Like others have already said the RF 100-500 is a game changer for birds\wildlife photography. I often use it with the 1.4 extender. I shoot both video and stills. I've set the camera up so that with a push of a button I' can switch from photo to vid...
