Hi Kenneth,
It sounds like you’re fine with the set up you have. The 80D with teleconverter gives you over 450mm (35mm full frame equivalent) with a constant aperture of f4 at the long end of the 70-200mm zoom. This is longer and faster than the 100-400mm that I used on my 1DX MkII. My shots were taken as the opportunities arose. The elephants (first shot) were at 2:00pm, the lion on his back at 6:00pm under Land Rover headlights and the buffalo around 4:00m - all on different days. The ability to shot wide open with a relatively fast lens is helpful. Basically I had one body and lens the entire time and the compact in my pocket when the need arose.
Enjoy your safari!
Andy.
