A7rII banding on both G/G2, oriented by light
5

I just switched from my continuous light source (LED panel) to a remote strobe with no modifiers (lots of glare). With this new setup I'm now able to get banding on both G and G2, but with a twist - G always bands above and below the light source, whereas G2 always bands to the left/right of the light source. This orientation holds true irrespective of where I place the strobe in the frame or whether I shoot in landscape or portrait. I verified this same orientation behavior on the A9 raw sample I have - I suspect the A7III will behave the same.

Here are G and G2 channel images with the strobe at the center, left, right, top, and bottom of the frame.
