No I don't.Gerald insists that CCD is good enough for that area (post here). On the other hand, my experience with CCD agrees with your statement here. Would you be able to share RAW files in this area (i.e. long exposure but not too long) to see the shadow recoverability, for a comparison between the 80MP Dalsa and the A7R-II?
Originally I speculated that in the 30 second territory the A7R-II could offer more details in the shadow than the IQ180, but now it appears that the A7R-II performs rather disappointing at 30 seconds when compared against its predecessor A7R.
Stop deliberately conflating what I was discussing with a totally different subject.
