Yes, this is strange. Professionals like the DXO staff do not make errors like this so I can only think that the subject lens used for the review was suspect.
I have had both of these lenses and found the MKII to be better by quite a margin on Contrast, Sharpness and AF Speed.
These results are quite a surprise to me as I was expecting them to be amongst the best in any class.
Am I kidding myself, is this lens really that bad? I don't think so.
What is the answer?
