Not sure if the question is directed at me. But no, I don't do wildlife photography.
But if I did, having f2.8 would certainly help. Again it's about extending the shooting envelope, the same way the A9 has done with some of its specs.
I don't always have to shoot at f2.8 but I would be able to. I can also use all the apertures between f2.8 an d f5.6 and also f5.6 and beyond. And whether at f5.6 or other, the f2.8 400mm's gonna be out performing the f5.6 max zoom so whatever way you like to cut it, that zoom is gonna be behind an f2.8 400mm prime, up to 2 stops or more.
