K-5 Low light/ High ISO dpreview vs dxo mark conflict

I just checked DXO Mark. The NEX-5N Low-Light ISO score is 1079 while the K-5 is 1162. In the DPReview website, the NEX-5N Low-Light ISO bar is longer than the K-5 when compared side by side. One of the reviews must be wrong.

Well the difference between 1079 and 1162 isn't that impressive, so I wouldn't pay to much attention to it. (0,14 EV or so)

As Ron stated, don't pay any attention. It's simply the differences in manufacturing tolerances and measuring techniques. If DXOMark and DPReview were to measure a dozen or so samples of each, the measured results would likely vary among the group by the amounts you've already noted.

I think the DP Review site is more likely to be wrong than Dxo Mark's site, although you have to remember that you are looking at 1/16th of a stop difference. Could be the difference from one camera sensor to the next, different testing techniques, etc that explain the difference.

Maybe DPR compares Jpg, when DXO compares RAW.
I mean, the very good part of the NEX5 n is the jpg engine.

I think they were put in different categories, it makes the 5n look better than it is. I would look at sample images on imaging resource for a better idea. (as long as they are in focus)
