Wow! Way more CA with the RIV. I don't understand why, but the a9 image is clearly superior.

I don't know, but a theory: if the lens throws equal CA in both cases it will show up more on the RIV. Say there's half a pixel width of CA on the A9- on the RIV that same aberration would be about .8 pixel width, so it would show up more clearly?

The RIV image started darker, LR brightened it up more.

Interesting. Maybe you should do the conversion with no adjustments at all.

Same shots without auto adjustments:

Much better. There's more detail with the 26mp of the RIV vs. the 24mp of the a9. The RIV clearly wins in this type of static shot, but it's pretty darn close. Now have the crow fly straight at the cameras and take 100 in-flight shots. I suspect the a9 will leap into the lead. Can you get that crow to cooperate?
