Some pretty cool scenery and I envy that guy in the wilderness.
It also show the advantage of having a light system not
requiring a tripod.

Agreed!

As a Fujifilm shooter I have my X-T3 combined with the XF 100-400mm f/4.5-5.6 OIS WR, and an X1.25TC.

That does not quite deliver the benefit of a constant aperture f/4.5, but my combo is weather resistant, and affordable until Fuji delivers additional, long, fast wildlife glass other than their non-zoom XF 200mm f/2.
