Quote:You can't win here. The near center approach puts the 5DS-R in a disadvantage in the "center" measurement compared to other cameras, skewing the results another way. It makes "superficial" comparisons of lenses on different bodies still a nightmare?
And the border/edge results are hardly lifted in the graph, you still will need a reference test with a lens tested on the D800 and 5D mk II...
Sorry, the tests were never meant for camera comparisons. Whether the 5Ds R looks bad compared to a D810 is completely irrelevant in my book.
Besides - once we switch to the next Nikon (and Sony) we'd follow the same approach.
The near-center approach would also favor higher quality lenses which would be a good thing.
