For more cameras (derived from DxOMark data) see DxOMark Photographic Dynamic Range Chart. However, data on this chart, when available, is considered to be more accurate. Note that the x-axis is ISO Setting and not a "measured" value. Keep this in mind particularly when comparing to the Ideal lines. Data in tabular form is in the resizable
The 5D Mark III had slightly higher resolution (22MP vs 20MP), but in almost every other detail the 6D’s sensor was superior. Shadow recovery, noise, high ISO performance, color science, and dynamic range were all better than the 5D Mark III, leaving me to write that article on why I chose the 6D over the 5D Mark III.
Here's the Nikon D750 @ 25,600 vs the 5d mark iv @ 25,600, both with 50 luminance NR in lightroom. Very similar. Note: for some reason the NR looks worse in the exported jpeg from the 5d mark iv than what I see in lightroom before export. Not sure why. When viewing in lightroom there's less of a difference. That’s a 2x price difference, less than the ~1.7x price difference between the 5D Mark IV and the 6D Mark II.” The $1,999 full-frame 6D Mark II (left) trails the $1,099 APS-C 80D (right) in Plus, the Canon 11-24mm F/4 is a really great lens and not something available from the other systems. But, I have to be honest, I would have loved to have some extra dynamic range from time to time, and my Canon 5D Mark II, and then Mark III, have definitely fallen short of the competitors in this category. How Much Dynamic Range Does the Canon 5D Mark II Have? Technically, there's a mathematical answer to this: the Canon 5d Mark II has 10 stops of dynamic range (you can find a long, technical analysis of that figure here). Compare that to the 15-stop Sony A7R iii, and it doesn't seem all that impressive. . 137 97 399 384 264 171 250 393 49
