the 70-200 f/2.8 VRII is very quick when set up optimally. I recently started on a moving subject using AF-S and focus was awful, but after correcting my setting to AF-C and Single point, it was fast and on the money.

AF-C, as you found, is crucial to maintaininggood focus when a subject is moving toward or away from the camera

I've had a lot of success using the older 300 f/4 AFS with the TC14E II teleconverter and the FTZ. The combination has been remarkable in picking up and maintaining focus on small birds in thick wooded or brushy areas. In this situation it has been much better than my D850.

This is an interesting observation

You seem to be referring to how small a subject an AF system can detect.

One way to learn this is to test a camera AF with smaller and smaller subjects until it gets AF wrong - it is this simple

The Z7 has more than 3 times the number of AF points of the D850 - though the Z 7 AF points cover more of the screen area.

The Z7 AF seems to me able to lock on a subject about half the size the D850 can achieve.

The D500 may not be as good as the D850 with small subjects when maintaining the same angle of view as the AF points then cover a bigger percentage of the screen area. Used with the same marked focal length to achieve more subject magnification I find small subject performance similar between D500 and D850.

A camera like the D610 with just 39 relatively large AF points is unlikely to be a front runner for your specific need.

Digressing slightly Nikon do not mention a minimum usable AF aperture in the specification for the Z7.

f11 works quite well with the 500 f5.6 and 2x. You should be OK with a 2x in place of the 1.4 when you need even more subject magnification.

In lots of ways good photography is much more about how equipment is used rather than the equipment being used.
