Is Dpreview working for Nikon by any chance? To begin with they missed the whole flare issue,then denied it and now this so called investigation (primitive compared to other review sites) that had to bring Canon in make dpreview feel good about their argument....Plain silly!
Sharpness,lack of CA,colors,contrast,minimal distortion and tones are simply superb. Its hard to believe such quality can come out of APS-C sensor!!
