We had the Nikon D4 for the weekend on loan from LensProToGo.com and wanted to compare it to the 2 bodies I own - the Canon EOS 5D Mark II and the Canon EOS 5D Mark III.
Here are some side-by-side examples of standard vs cinestyle picture styles as well as moire and sharpening on all 3 cameras as well as I threw in a quick sample of using the cinelook FCPX plugin to do a 'quick' grade (blog.planet5d.com/cinelook affiliate link).
It is a shame that the Nikon D4 is soft in video!
I didn't make time to explore the different crop factors on the Nikon D4 - tho I have been reading that the 2.7 crop makes the Nikon D4 shine for video (it appears much sharper).
Thanks for reading planet5D.com!
