Second, you are correct; however, with new AI software, he can recover some of the lost sharpness
Third, I've never seen a recommendation to combine teleconverters, so I agree with you.
Fourth, Since he already owns a costly 400mm 2.8 lens, purchasing a 600mm f4 at $13,000 seems a bit outrageous since it appears he is not a professional selling his work. Many people use teleconverters but accept that they will not be tack sharp.
Fifth, with a 600mm lens, you will not need a teleconverter for most shots unless you migrate into wildlife, where an 800mm lens is better. However, either lens requires deep pockets.
Sixth, I also say good luck and keep on shooting. However, I'd only use the 1.4 or the 2, not both.
Seventh is not part of the question but from my personal experience. I recently shot a local rodeo from the stands. Being at the far end of the arena, I used a 1.4 tele on my Nikon 200-500 f5.6 lens. This was mounted on a Nikon D850. This, in effect, made my lens one stop higher, which wasn't the effect I wanted. I switched to my 70-200 f2.8 and exposure was much better, but I lost one stop when I tried the 1.4 tele. It may not seem like much, but one stop was noticeable.

I am actually a professional soorts photographer. Dont often post sports photos because historically the corporation I worked for claimed they owned the photos. They no longer claim that so I am now posting some sports photos.
As to not posting in the bird sectiin I only posted in the main section because this was about converters not birds which is why gwilloams posted people being pulled on tubes behind a boat.
Also I think most of the argument about sharpness of the original images ia more about exactly where the focus point is, the narrow depth of field and the post processing or lack thereof. For example the beak of the wren is not particularly sharp.
As to a 600 f4 I thought about getting one but the 400 2.8 with a converter covers essentially all of Nikons big lenses while only buying one. They make the 400, a 600 f4, a 800 f6.3, well the 400 with the built in 1.4 is a 560f4 so almost the equivalent of the 600 f 4 and without the 1.4 converter but wirh the 2x attatched it is an 800 f6.3, so in my view it is more versitle.
Also for some of us there is no such thing as a big enough lens. A couple years ago I started shooting softball from behind the outfield fence. It allows you to shoot both batters and defense and baserunning at all four bases. All you miss is catches in the iutfield. Well sure enough they wanted me to shoot baseball from the same place and since fields are much larger even 1120 is marginal for home plate.
As to rodeo I have never shot from the stands. A 200_500 is pretty good for every event except team roping if you are in the arena.
