Every time a camera comes out, nerds keep a close watch on DxO Labs to see how the image sensor will measure up to others in the camera benchmarker's battery of tests. DxO just released its ratings for the most anticipated camera in years: The Canon EOS 5D Mark III. CNET was there to document the whole process.
Given how much people seem to love the 23-megapixel Canon EOS 5D Mark III, it's surprising that it didn't score very well on DxO's scale. It barely beat out its predecessor, and it was absolutely demolished by the excellent 36-megapixel Nikon D800. In fact, DxO found the 5D MKIII's low-light performance—its hallmark—to be pretty paltry in comparison to its rival. In our tests of the two cameras, we saw advantages to both, but would never have chosen one so definitively over the other.
