DxOMark has published their test report on Canon EOS-1D X Mark II. Unlike many other review the result of DxOMark is primarily based on sensor performance. The top position still belongs to Nikon D810 which scores 97. The Canon EOS-1D X Mark II scores 88 with very good low light performance. The Nikon D5 also stands in the same line but its main strength is in high ISO performance.
“The Canon performs exceptionally well. Not only does it have a wider useful dynamic range at base and low ISOs than the Nikon, it’s not far behind the Sony, and that small difference won’t be noticed in use. The Canon sensor continues to offer a wide dynamic range at every ISO setting, improving on the Sony from ISO800 onwards, and falling only slightly behind the Nikon’s strong performance from ISO6400 onwards. Indeed, the difference at most is around +0.6EV. Canon cameras are known for high ISO noise performance, and the Mark II surpasses both the Nikon and Sony by nearly +0.5EV.”
