Don't expect such a lens to be anywhere near as hand-hold-able. The front element needs to have 4.5x the area; the lens needs to be longer, etc. Even a 600/5.6 DO prime, would be as big and as heavy, or a little more so, than a 400/4 DO with a 1.4x TC, and add to the zooming, and you're looking at something at least 7 pounds, minimum.

What I wonder about is whether Canon will eventually start making lenses slower than f/5.6, as AF ability at higher f-numbers improve, especially with mirrorless cameras with EVFs.

A 200-600/5.6-8.0 zoom could be very hand-hold-able. Even f/7.1, if they break from their whole-stop silly standards.

would that be a "L", EF or just an EF-S zoom? makes a big difference! looking at Tamron and Sigma, and nikon it can be achieved (150-600mm) but it will be just a matter of economics for canon!

I was assuming a lens the quality of the L and DO series. Those 600mm 3rd-party zooms are not as rugged or as sharp wide open (although they're fine when you fill the frame and don't have to crop much).
