I just wanted to test my Canon 1DC in 4k with the Dragon using the same lens etc, was just for me but thought I might as well share also. Even cropped down to the same aspect and resolution the Dragon has more detail, especially noticeable on distant roof tiles. (.R3D included for reference). Shot at ISO 800 CLOG on the Canon, graded down to ISO 250 on the Dragon. Lens used Zeiss Otus 55 at f4. In tests found 'Detail' in REDCINE-X to give a plastic look, tiff file with detail at 0.
They match pretty well and would intercut just fine. Slightly unfair advantage on the Dragon but under the conditions I would shoot.
