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.
