Yes, so clearly, the 2.0x is not the issue.

I noticed that you have the 100-400 in your gear list. I'm very interested in your a9+100-400+2x experience. I'm curious if the 100-400 can be a viable lightweight option. Thanks.

Let me see what I can find.

I was thinking more about the shooting experience, AF speed, keep rate compare to without the 2x, etc. Thanks.

It's pretty good with the a9, with great tracking and reasonable acquisition speed.It's not the ultimate. On the a9 even the 600mm GM slows with the 2.0x. Going from the bare lens to the 1.4x you notice little difference with acquisition and tracking, but you will notice a difference. It's not horrid, but I wouldn't use it for really fast BIF.
