This is an interesting comparison. I wasn't expecting the 300 + TC option to track or focus as good as the A9 + 200-600.

I suppose even with the TC the 300 is still usefully brighter than the 200-600.

What about how they focus? The A99 will focus at full aperture and stop down to take the photo.

Doesn't the A9 focus at the taking aperture?

I think some of the A7x cameras can be set to focus wide open at the expense of a bit of speed of operation. No idea if the A9 can do that ir indeed if I am correct about focusing at the taking aperture but it's something to check out.

I took up using the x2+300mm over from using x1.4+500mm (sigma - it costs 1/3 of sony).

My idea was that I can take off the x2 when I want to shoot nocturnal wildlife using a telephoto, so the f2.8 300mm makes sense. Also, more than one review stted that A99ii was able to focus better than the A9 at low light.

As far as I know, and Im not 100% sure of it, but the wide open to focuse and stopping down to shoot is still the case for mirrorless. reason being, you cover up part of our sensors otherwise.

Interesintgly enough, I have got a Minolta AF 500mm - mirror (~4.5" in length, 635g, with fixed f8 (front mirror - like in a telescope). It was my favorite for some time and worked well for me even having it supposedly "stopped down". Focused really fast. As far as miror quality, they could have done a better job, though it is not far off the standard ones in terms of image quality.

Hope this provides you with some useful info, while answering your question as best I know for now.
