It really boils down to YOU. WE can't and shouldn't attempt to steer you one way or another. They are both fine cameras. Just remember there's no such thing as a free lunch. Your offsetting resolution for speed.

I had a A7RIII but sold it and bought the A9. I felt that quite often I'd be able to do more cropping with the A7RIII but then need to apply more NR and the end result didn't look that much different.

I think we have been programmed to think more megapixels are better and in some cases that is true but there are compromises.

This is a large investment and you may want to consider renting both cameras and that lens to test out ahead of time.

A few other comments:

  • With the A9 you can shoot above 1/8000 of a sec without any perceivable distortion using the electronic shutter. To this day, there is no other camera on the market that can do this and yes, I do use that fast of a shutter speed for capturing small birds-in-flight.
  • If you shoot video, the A9's (both of them) do not offer SLOG to protect highlights when filming outdoors. Why they've never put this feature on the A9's is beyond me.
  • When I had the A7RIII I used it for some specialized projects requiring HUGE signage. It was a fun camera to use and if you do something like that or crop the hell out of your images, I'm sure the A7RIV will be a good choice. You will fill up hard drives faster with that resolution however and processing images will take longer too.
  • I rarely use 20fps with the A9. It takes a long time going through a lot of images once you have taken them and unless it's a really fast bird, they all look the same. I use 20fps sparingly. (Most of the time, I'm at 10 fps.)

And then there's the A7SIII. I just bought one for nature video work and the camera is incredible and the 12MP stills look really nice.

I've been around DSLR's for a long time and I remember drooling over the Canon 1DS when it was announced with its astounding 11 megapixel sensor. I took a lot of fine pics with that camera.
