Just more confirmation that DxO is a total joke

Best comparison I can make, is DxOMark is to camera gear what The Food Reviewer is to Nutrition:

We do not get information about performance at specific f-stops, center, edges or corners, flare, vignetting, CA etc.

Actually, you do get most of that information (not flare, but resolution, vignetting, CA across the frame and aperture range).  But it's in the Measurements, not the Scores. 

In the case of lenses, their scores are another example of DxOMark ≠ Reality.

There's a lot of talking recently about DxOMark sensor tests.
I was utterly shocked when I saw the results. My question is are their resolution tests accurate?
Can somebody please tell me: are these DxOMark tests right or not. Thank.you.

I have seen so many crazy results at DxO regarding lens tests that I never even bother to look there now, ever. They have weird results after weird result. 70-300 non-L being much sharper at 300mm f/5.6 than the 70-300L. It might have even been called sharper thanb the 300 f/4 prime. I think they had the 70-200 2.8 IS, at 200mm, sharper than the 70-200 2.8 non-IS, sharper than the f/4 IS, sharper than the f/2.8 IS II or something crazy like that.


That said, their sensor tests, something totally different, DO seem to be very good and definitely something to pay attention to. I go there first, when it comes to sensor data.
