Comparing the Dynamic Range of the Sony A7 III, Canon EOS R, Fujifilm XT-3, and Nkon Z7

Dynamic Range of the A7III, EOS R, XT-3, and Z7 Compared

Last Updated on 12/09/2018 by Mark Beckenbach

Let’s see how the current flagship mirrorless cameras stack up against one another in terms of dynamic range.

In the future, when we look back on 2018, we will remember it as the year the photography industry moved full steam into the mirrorless world. Never before have so many compelling mirrorless camera options been available on the market at the same time. The Sony A7III was the first, announced back in February of this year at WPPI, and it was followed by the Nikon Z7, Canon EOS R, and the Fujifilm XT-3 being announced within days of each other that summer. Photographer Michael Andrew recently did a comparison of the dynamic range between these four mirrorless cameras in his latest video, which you can view after the jump.

Andrew’s dynamic range comparison examined the noise artifacts from each camera system by capturing images fired from a strobe at each system through a Stouffer Industries Transmission Step Wedge strip containing 41 minuscule ND filters. These filters gradually increase at 1/3 f stop increments, and subsequently review the images in Adobe Camera Raw to determine the point at which you can no longer differentiate between adjacent ND filers on the Stouffer strip.

At base ISO, Andrew’s comparison found the Sony A7III to have demonstrated a slight dynamic range advantage over the Canon EOS R, Fujifilm XT-3, as well as the Nikon Z7. The Sony A7III, Canon EOS R, and Nikon Z7 were at ISO 100 while the Fujifilm XT-3 was at ISO 80. At ISO 1600, the Sony A7III continued to lead the pack in terms of dynamic range, with the full frame Canon EOS R and the Nikon Z7 falling slighting behind but performing better than the crop sensor Fujifilm XT-3, which began to show considerable noise.

Have you made the jump into any of these mirrorless systems already? Did this comparison test match your expectations of how each camera system would perform? Let us know in the comments below.

    Correct me if I’m wrong but if the XT3 was set to ISO 80 in this test then it was always going to show less DR than the others as this is a pull setting. It’s base ISO is ISO 160.

    Let’s compare photograpy devices and then put the results in video. Brilliant!
    Are there (outhere) only couch potatoes, unable to read and look themselves at image files, needing to be told what they should see?

    I recently switched over from a Canon 5D markIV to an A7rIII and am very impressed with the dynamic range of this camera. I have a lot of latitude in camera raw to fix shots I might not get quite right and it minimizes noise drastically. Very happy I went with a Sony mirrorless!
