Stunning Reversal

This a comment for this page on the website
It could be said, these measurements, having arrived so late, change nothing. But to me a game changer.  The numbers provide needed stunning confirmation that as used with the A7rII, these lenses, that were suffering from lower numbers tested on the original A7r, are every bit the equal, and in many cases significantly better than the best from Nikon, Canon, Sigma and others. Higher pmp than that achieved by the Canon 50 megapixel camera; higher than achievable by the new Canon 5D Mark IV and higher even than numbers from the Nikon D810. In fact in the case of the Sony FE90mm f2.8...PMP that achieved 100% of actual MP...Maybe the first time ever in this data base. Suddenly third party lenses with semi functional adapters are near irrelevant. Long time in coming...but congratulations due to Sony.

Great comment. Interesting to see the zoom scores too. The 24-70 2.8 has a sharpness score of 28 on the A7RII compared with 17 on the A7R.  Got to question why that lens was not tested first on the A7RII - though in fairness that jump in performance is surprising.
