Perhaps the DxOMark Sensor rankings site is old hat to many of you, but I recently stumbled upon it and was surprised by some of the rankings. I was not surprised to see the Nikon D3 take first prize overall for sensor quality, but other scores are not what I expected. For example, the Nikon D300 did not score so well in the "Low-Light ISO" category. It came in #21, scoring worse than the Canon 1000D/XS (which came in at #18). I thought low-light ISO performance was the D300's strong point. The D700 took first place in that category. I was also surprised to see the Samsung GX 20 get one notch higher than the Pentax K20D, since they use the same sensor. Strange. Also, in the category of "Dynamic Range", the first three slots are taken by cropped-sensor cameras. Not what I would expect. The site claims these are objective scores, based on measurable results. I'm curious to know how reliable the scores might be. Any ideas or opinions?
