a7RM2 + 10-18mm: nope

This is not a rigorous test, but I think it's enough to convince me that the 10-18mm is no substitute for a FF UWA lens for the newest Sony. Based on the Brian Smith test with the a7R , I hoped that the new sensor design would be more tolerant of this crop-sensor lens.

What I'm seeing is that the corners are not good enough for me to consider this combination. I also found out that my lens appears to be decentered.

Is my testing just too casual to draw a conclusion from it? Anyone else tried this combination?
