okay, I don't have personal experience with 200-500 f5.6E besides testing a friend's; it will struggle at f8 for the AF of a DSLR, even the latest Nikons. It does better on a Z6 or Z7. Hands down, the 200-500 is still a big bargain especially for many subjects in wildlife photography
With the correct - rather matched - pairing the TC14 III is excellent. This is with a selection of faster primes but also 70-200 f2.8E and also the very expensive 120-300 f2.8E SR, and the other 'exotic' prime telephotos. Nikon has a compatility lists. The industrial speak is the TC14 III was upgraded for the E aperture Nikkors, and it's probably no mistake Nikon launched it with the 400 f2.8E FL, with which it is excellent.
A Used 300 f4E PF is probably the most accessible Nikkor among these selects.

I love my 200-500 as well as my 300 PF and will be using both with my future D850 (not delivered yet). Considering the D850 is heavier than my current D7500, I am trying to find ways to cut down the weight of my gear (for longer hikes). So my thought was to keep my 200-500 for shorter hikes...

I've drawn together the following summary from a most enjoyable 3 weeks recently hiking in the lowveld savanna thickets in Greater Kruger - picked out some images as examples (more on my instagram). This also included 3 days within the KNP self driving in more open habitats, although I tended to...
