I think skin tones are very good on a D5200. On Mai 13, I got some issues with the daylight who changes all the time. Juan Miguel wasn't ill but he's a South American and he needs sun after a long winter in Paris.
You can check skin tone on this samples : Some secondes (in and out point and save as... in MpegStreamclip) of original D5200 files.
127,1 mo ; 7 differents skin tones. (green tone on the DSC 0178 is a wall green reflexion)

If D5300 doesn't produce FPN, I want one.
