Yeah but it's 100-500 so probably at 400 it might similar to the existing 100-400, maybe 5.4 at 400? If that makes the lens smaller, lighter and more affordable, I'm in.
Also r bodies autofocus at least to f11, so the 1.4x should autofocus.
Oh yeah, I forgot it is 500 ...I would be surprised if it was anything but 7.1 @400 tho ....MAYBE f6.3
I have heard that AF @ f11 does "work" - but not that great - at least with the current bodies.....
