5DsR resolution vs. 7D MkII

The 5DsR and the 7D MkII have the same pixel-density, but the full-frame 5DsR has more than twice the sensor area than the crop-sensor 7D MkII, so I thought it'd be fun to compare.

I compared at ISO 400, 800 and 1600, because these are my prime bird-in-flight ISOs, used to allow high shutter speeds. I used my very sturdy Induro C414 tripod and heavy duty Arca-Swiss Z1 ballhead. I used Liveview 10x focus with the 7D2 and 16x with the 5DsR. I cropped each of the images to 1584x1056p so that we see the same number of pixels with each camera, possible due to the equal pixel-density.

Here are the resulting images, process with DxO Optics Pro 10.4 with "No Correction" except geometric distortion correction was applied.

Keep in mind that neither is sharpened and can be improved with a tiny bit of post processing.

Still, you can see that the 5DsR's ISO 1600 is almost as sharp as the 7D MkII at ISO 400!! The 5DsR neutralizes the anti-aliasing filter, adding to clarity and that may be the whole reason for the difference. I also think that the color rendition of the 5DsR is superior also, but that could be the Raw converter's profile being better for the 5D than the 7D. Don't know, but it's better, to my eye.

Needless to say, I'm really pleased with my 5DsR. Here's a real world shot, at ISO 1600, with almost no crop:
