next PZ lens test report: Sigma AF 12-24mm f/4.5-5.6 HSM DG II

5 stars on Price/Performance? Why? After all, the most coveted aspect of this lens is its 12mm ability and there, the actual border resolution figures as seen in the Field Curvature section is very poor.



The chart below assumes a "flat wall" scenario where the center is set to the optimum focus distance - imaging that you stay in front of a flat building and simply use the camera's AF.
May I guess that many users will use it exactly like this?

If a lens offers something that is not provided by any other one it is almost a 5* lens by definition in my book.



We were criticized for not providing any hard guidance on field curvature - now we do.
