Well, here's me with egg on my face! I’ve just had a look at the camera original EXRs and the Helium does indeed have more resolution. So that’s that one sorted. Now we just need to get to the bottom of this NR thing!

I'm finding that when everything's executed well, I can get pretty much the same resolution and detail as with my A7R, though the Helium has nicer color before grading when using IPP2.
Ah, now that’s interesting! Have you done a direct comparison? Same lens/stop/subject (ideally a focus chart)?
I’m not a 100% sure if having the option NR settings in the Raw control panel is quite the same as there being no other noise reduction elsewhere in the image chain.
I’m assuming there’s already a separate process for dealing with Fixed Pattern Noise. So there’s no reason why there might not be others.
