Canon 5D Mark IV Dynamic Range
I just posted a comment on DPReview regarding a comment they made about the Canon 5D Mark IV and Dynamic Range. Below is the full comment repeated:

Regarding the review comment about the Canon 5D Mark IV, "Although its dynamic range still isn't best-in-class", I would point out that, according to DXOMark, by ISO 200, the Canon 5D Mark IV dynamic range (DR) is the same as the Nikon D810. By ISO 400 the Canon 5D Mark IV leads the Nikon D810, and continues to lead in DR through all higher-sensitivity ISOs.
The Canon 5D Mark IV leads in high-ISO dynamic range, and in SNR 18% for that matter, where it counts. It would be appreciated if DPReview would accurately represent the facts. (Exposure Latitude and ISO Invariance are interesting, but not representative of Dynamic Range by itself.)
In short, the Canon dynamic range ranks with the best sensors out there for High-ISOs (along with the Sony a7R II).
This is not a slam against the Nikon D810, which is an extremely well designed camera, nor is it a slam against Nikon in general. I own lots of Nikon SLR and dSLR bodies, and truly enjoy and appreciate them as fine cameras.
In support of my claim:
(Feel free to corroborate: https://www.dxomark.com/Cameras/Compare/Side-by-side/Canon-EOS-5D-Mark-IV-versus-Nikon-D810___1106_963)
The yellow freehand line surrounds those ISOs where the Nikon is better. The red freehand line surrounds those ISOs where the Canon is better. Significantly, the Canon sensor is better when the cameras are DR limited, which is at High-ISOs, and that's the region where reduced DR matters most.
