Canon 1D X DxOMark Score is out now and the figure will again start hot discussion all over the web, the current 1D X score is similar to Nikon D3s Score (announced at 2009),
The 1D X’s most obvious competitor in the professional DSLR space is the Nikon D4 and its predecessor, the Nikon D3s. Based on their sensor scores, it looks like the Nikon D4, which was announced a few months after the 1D X and also hit the market this summer, can deliver better sensor performance across the board (and sells for $800 less than the 1D X), whereas the Nikon D3s (which sells for roughly $1,600 less than the 1D X) is much more similar, though the three cameras perform similarly in low light.
Review outside the DxOMark Lab also have a mixed response – See Canon 1D X vs Nikon D4 High ISO Test – by focus-numerique and xerodigital.
