Canon EF 400mm f/4 DO IS II USM Lens Image Quality Results from the EOS 5Ds R

Image quality test results from the Canon EOS 5Ds R have been added to the Canon EF 400mm f/4 DO IS II USM Lens Review.
 
The 400 DO IS II review was completed before the 5Ds R existed. To get these results added to the site, Canon USA loaned us another copy this lens. Under the scrutiny of the ultra-high resolution 5Ds R, the center of the frame is showing a touch of softness in the center at f/4 in this copy of the lens, but this lens performs impressively otherwise.
 
Here are some comparisons to get you started:
