DxOmark tested the FE zooms on the Sony A7rII and the leader is….

DxOmark tested almost all FE zooms on the Sony A7rII. And the best lens is the [shoplink 47257]70-200mm f/4.0 G[/shoplink]. I suspect the real leader will be the [shoplink 48791]new 70-200mm f/2.8 GM lens[/shoplink] once it gets tested. By the way Sony…when are you shipping the lens again?

The top ranked zooms are:
70-200mm G at [shopcountry 47257] 24-70mm GM at [shopcountry 47915] 16-35mm Zeiss at [shopcountry 49023] 24-70mm Zeiss at [shopcountry 49022] 28-70mm Sony at [shopcountry 24940] 70-300mm Sony at [shopcountry 47527] 24-240mm Sony at [shopcountry 34245] 70-200mm GM at [shopcountry 48791] (not tested yet and probably the real top ranker)

DxOmark also posted the full 70-300mm FE results and the good news is that the lens beats the competition:

Against rival models from other makers, the Sony is a very competitive performer optically. Indeed, it is a slightly better performer than the $1,600, L-series Canon equivalent, introduced in 2010, and is several leagues ahead of the Nikon.
