Quote:Regarding astigmatism once more - the 16-70mm is hardly the only lens affected by this. Essentially all lenses till 50mm are. 
Not many lenses show such a poor border performance at f4 in your MTF tests, and yet seem to do a bit better in the images shown. Hence my suggestion to shoot a few MFD shots to see if the astigmatism is visible. 

My example lens (the 20mm f3.5) shows what I mean.
