DxOMark posted their Canon EOS-1D X Mark II sensor review and test results: The Canon EOS-1D X Mark II achieved an overall DxOMark score of 88 points, making it the best-performing sensor in the company’s range. No surprise!
Canon EOS-1D X Mark II vs Canon EOS-1D X vs Canon EOS 1Ds Mark III: Expanded low ISO DR
Canon EOS-1D X Mark II vs. Nikon D5 vs. Sony A7 II: Excellent all-round performance
Conclusion from DxOMark:
This is a well-deserved result for Canon, and this versatile sensor should prove attractive to a wide range of photographers, including those that work in multiple disciplines. The wide dynamic range at low ISOs should appeal to all photographers, but especially those using it for landscapes, and the low noise at high ISOs will also appeal to action and sports photographers. Although the new model is aimed primarily at that market, the increase in pixel count over its predecessor now matches that of the earlier EOS-1Ds Mk III, a model that’s still highly regarded for editorial and commercial work. It is not too much of a stretch to view the new EOS-1D X Mk II as the natural successor to that camera, and its wide range of capabilities, including DCI 4K video, make it look highly tempting. Sure, it would have been great to see a higher pixel count, but overall, the sensor performance offers photographers the versatility to tackle a wide range of assignments with just one camera.
