Now Nikon have the 400 f2.8 with 1.4TC in I believe that will become the norm for many of the superteles.

What's not to like, buy a 600 f/4 get a 400/f2.8 for almost free, and can switch at the flick of a switch. Will be a helpful kit with the Z9.

If the Canon's can be engaged while the camera is active like the Z 400 f/2.8 TC then it will be very exciting. The older EF 200-400 f/4.0 TC and Nikon 180-400 have all kinds of warnings about not to engage the TC while you are focusing or VR/IS is active. The new lens lets you flick back and forward while shooting at peak action and that's what makes it even more exciting. Built in TC's seem to be how we make super tele lenses unique for mirrorless, or perhaps just to add some bulk to an otherwise long empty stem.
