Looking good.
What I find interesting: I noticed at its introduction that the 70-200mm f4 has the same optical formula for most part as the Canon 70-200mm f4, the front/mid groups are the same, and even the size is basically the same. The back groups have more in common with the Nikon f2.8 VR II.
The results from your test are almost carbon copies of the results from Klaus' Ef 70-200mm f4 L IS USM on 5D mk II tests... the MTF graphs are very similar, as is the CA performance.
Nice lens.
