The first sample delivered miserable results throughout the range whereas and the 2nd sample showed a very soft output on the left image side. Honestly, we consider two samples to be enough so the resolution observations reflect the results from the 2nd sample (based on the center and right image side).

That's an expensive lens.  At least with the 16mm, it was the least-expensive Sony-manufactured Nex lens -- maybe still is.
