LensRentals also just tested the lens (only resolution). They weren't impressed either. The big plus with version II seemed to be less sample variation then the version I.
And didn't we think that the CZ 24-70/4 for Sony E cameras is bad... If it is, then what do we call this?
So on top of the "meh" optical performance, we have once again issues with quality control (decentering, focus accuracy). I seem to remember that the mk1 was also had issues with this.
So much for the red ring being an guarantee of quality....
