next PZ lens test report: Sigma 12-24mm f/4 HSM DG ART
#18
If I chose the +2 slice (outer region) the chart would look like this AT 21mp ...

 

This gives probably a more realistic figure what to expect in the real life (at 21mp, it will still be much worse at 50mp).

 

Again ... I don't like to play that field curvature game but it is part of the whole picture.
