Check out this https://photographylife.com/reviews/sony-fe-2x-teleconverter article and the image quality from the 100-400+TC2.

I think you will find the a9 AF works just fine with the TC2 - I shoot almost exclusively at 840mm with my a9+200-600+TC1.4. Dn't expect to get anywhere near the same performance from the a7riv.

I find that for sharp images with lots of detail it is more important to fill the frame and get as many pixels on the subject as possible. That means getting close to the subject.

Potentially interesting option for use with an A9 but when added to the f/5.6 max aperture Sony 100-400mm GM, you are left with a f/11 max aperture. Somewhat limiting. Also, I assume any weakness due to copy variation would be accentuated. Agree that the 2xTE would be much better on the A9 vs the A7RIV.
