Main issue I'm seeing (and again it was overcast today) is very narrow DOF, even at considerable distances.

Yes, I have the Sigma 600mm F8, and I've tried Samyang 800mm F8's. It makes me wonder how useful long F2.8 lenses are really for example the Sigma 200-500mm F2.8.

It seems like F5.6 for the AF sensors is plenty. The new Sony FE 400mm F2.8 doesn't make much sense to me. None of the E-mount cameras have even a single F2.8 AF sensor. Though it does seem like the on-sensor AF points somehow benefit from brighter lenses while dedicated AF sensors mostly do not.
