Re: DxOMark promises to retest the GX7

 But the main point here is that DxO's slipup with regard to lens tests on the GX7 doesn't necessarily mean that all their results are useless.

I must admit that this test (*) has me thinking. In this particular case, the results are too unreasonable to be taken seriously. But what if they had been only slightly off, lets say 10% or 20% or so? Then the slightly off numbers and curves are scrutinized and compared side-by-side with other results that are also hard to tell if they are accurate or not, because there is no way for an outsider to verify that.

(*) Another example was Jack Hogan's resolution curves, calculated from shutter-shocked images. But that was quickly sorted out because the input data was available and known to be garbage.
