next PZ lens test report: Sigma 12-24mm f/4 HSM DG ART
#17
Here's the "field curvature" at 21mp.

 

Again - this looks MUCH WORSE that it is. If I would take these readings with a +/-2 slice horizon the chart wouldn't look that extreme anymore.

As mentioned I am therefore reluctant to providing these figures.

 

So at 21mp, the f/11 figures is livable again.
