As you've likely read, I've been using the Canon EOS 5Ds R as my primary camera since it first became available. While I still love the image quality this camera produces, the 5Ds R is beginning to feel aged. In particular, I wanted to know how the dynamic range of the new Canon EOS R5 compared to that of the 5Ds R. Some additional testing, over and under-exposure captures from the 5Ds R, makes that comparison now available in the site's camera noise comparison tool:
Canon EOS R5 Dynamic Range Comparison with 5Ds R
In that 2-stop-overexposed comparison, the R5's dynamic range is clearly superior (keep in mind that the brightest color value is below RGB 255,255,255 in the base exposure).
As expected, the +3 EV comparison more clearly shows the R5's improved performance.
