Canon EOS 1D X Digital Camera Review

Dynamic Range

Our dynamic range results showed the Canon 1D X topping out at an impressive 8.43 stops of range with a signal to noise ratio cutoff point of 10:1. It fell off from there, predictably, but noise didn't really begin to drag down dynamic range until ISO 6400 and above. The superior performance at ISO 100 puts it above the Nikon D4, though it falls into line with the D4 through most of the rest of the ISO range. The two camera are otherwise practically neck and neck, though, as both cameras employ their full-frame sensors to get great results even at high ISO speeds. More on how we test dynamic range.
