DXO's lens test have always thrown up some weird anomalies that appear to fly in the face of owner experiences of the same lens+camera combos. Who knows why? We can only speculate. I do wonder if they test multiple copies of each lens - I'm guessing they don't. There can be a lot of sample variation, even with expensive G lenses (sadly). One thing that doesn't surprise me - Tamrons sometimes out-resolving Sony G lenses - I have seen that in action myself with the 70-200s - Sony may have nailed SSM AF but at the long end the Tamron 70-200 can be sharper than the Sony G. If the new Tamron long zoom is as sharp or sharper than the 70-400G then they will have pulled off a miracle - it's going to be interesting.

Anyway, maybe DXO should get back to doing what they do best, which in my mind is making a very good raw processor, DXO Optics Pro.
