The noise is awful for being ISO250 on an A7S. What is causing this amount of noise? Maybe ETTR would have taken care of the noise?

I dont know....I'm struggling with the A7s.
It was a long 26 second exposure...the noise is coming from that. I know it's a pain, but this is why I keep Long Exposure Noise Reduction switched on.
And this is a good study in why it's great to have both an a7R and a7S. For this shot, the exposure settings make the a7R a vastly better choice. But, if you wanted to take the same picture with a faster shutter speed and higher ISO, then that would favor the a7S.
How about this as a rule of thumb: if you want to use your tripod, then reach for the a7R. But, if you want to take a handheld shot in low-light, then reach for the a7S. And for handheld shooting in good light, take your pick: either are great.
