Thanks for sharing the samples, Markus...
One would inevitably compare this lens with the 16-35mm VR... This one does not have a gold ring but it is definitely more affordable, lighter and also the MTF chart looks quite ok. Furthermore the geometric distortion at 18mm looks also tolerable. CAs are there of course (if you check 100% views) but the sharpness at corners is quite good. Also I found the field curvature quite tolerable too. I'm not an expert but Nr. 6 looks ok to me...
