Re: Pentax K-1 II: Class leading dynamic range and ISO invariance

Just as a point of reference with regards to the A7r3, I believe it is only ISO invariant from ISO640-Max (from ISO100 it is invariant up to ISO640), so I would assume the same test run but starting at ISO640 or above the two would match.

Of course there is still added value in being invariant starting at ISO100 instead of 640, but in the test run the Sony is pushed outside of its invariance boundaries.
