Next PZ lens test report: Canon EF 11-24mm f/4 USM L
#7
A typical ISO 12233 chart is more in the range of about 4-5' wide by 3-4' tall.  I do not know how big Klaus' chart is, however.  Testing anything under 20mm on FF you are basically kissing the chart.  11mm looks quite ridiculous. 

 

The corner vs center results may also be influenced by the chart lighting.  This is an issue even the people who wrote imatest do not know how to quantify the effects of.
