Pipe dream. You need to try the 400mm DO. No zoom, but you are only going to use it at the long end anyway. With a 1.4x you get to your 560mm at a reasonable f5.6.
Pipe dream? Actually, I have shot and like the 400 DO IS II. Not bad, but the zooms are much more versatile for what I shoot. It is a great lens for airshows, easy to handhold and pan. If they come out with an RF 400 or 500 DO, that will probably be my next lens. That said, I will always have something like the 100-400 II in my bag. I would even be happy if they would release a RF 200-400 w/1.4x as long as they could shave off 2-3 lbs similar to what they did with the 400 & 600 III.
