next PZ lens test report - Sigma 14mm f/1.8 DG HSM ART
#11
Is the field curvature constant at all distances or does it change during various distance settings? Asking in general. With it's 4 aspherical lenses it's a challenge to design anyway.

 

When the sky will become a bit clearer, I like to verify how much of an influence this flaw has. To me it's better than your rating, but I have different prioirities.
