What is the difference between "flat surface" noise and "underexposed or high-ISO" noise?
Any chance you can give us an example image?
I"m finding more noise on flat surfaces like the side of bus. It's really on areas that are on edge of being out of DOF. I'm over reacting certainly. I think there is some validity to this, but not sure how bad it is. comparison shot is with a7r & a7rii. looks pretty good to me. I can put raw files in a drop box. Will have to wait til I get back from 10 day shoot. Thanks
Capture One(I don't like) imports with no noise.
Just note that Capture One applies some noise reduction to every image, even if the NR sliders are set to zero.
And - in my experience - it is better in general, in terms of noise handling, than Lightroom.
Interesting Keith. It's not in every photo and I'm still trying to figure it out.

Your initial screenshot pair is ISO 80 and your lower screenshot shows no shot parameters to understand the ISO from. I see no noise-specks in either screenshot just a little noise grain as expected.
Hi SS. Lower shot iso 80, f 5.6, 1/320, hand held, ibis on Loxia 35
New shot, which illustrates this well is loxia 35 @ f2, ISO 80 1/20th. After pouring over a couple hundred photos, areas in focus are fine. It's out of focus areas that are much grainier than previous cameras I've shot. There should be no noise on the camera here and grain behind it, just out of reach of the DOF because of f2, should be blurred, not noisy.
