DxO and medium format
The DxOMark site has published results for various medium format digital backs including Hasselblad, Leaf, Mamiya and PhaseOne.
The results don’t come as a big surprise to me—while medium format is exceptional in some ways, it’s not so exceptional in others.
Lost in the numbers is the crucial fact that medium format in most cases skips the anti-aliasing filter, and this alone makes it look so much better for many types of images. Numbers are useful, but remember, there is no family which has 2.5 children!
