No idea, I don't own a D7100
Point is that the D7100 video results could well be better in the hands of a better videographer, but could be considerably worse in the hands of someone without a clue and of course the same must be true of the K-50.
Currently in my humble opinion the MX-1 produces the nicest looking video IQ 'out of the camera'. By 'nice' I mean way less aliasing and moire, less smudging of distant detail and less hiss from AGC. But you have to shoot with contrast and sharpness completely off.
Of course, you don't have any manual control with the MX-1, but I'm always very satisfied with the clips. (The MX-1 is a rather nice camera, period)
The K-50 and the K-01 I do have and while I feel the video is crap for your average tourist holiday clip use some members here with more skill and time than I have managed to create some good results using the K-01. I find it suitable for 'near' subjects, but not general deep dof work, not at all. The K-50 would yield similar results for those folks.
As a test, here's pretty much my first few clips shot with the K-50 and 18-55mm kit lens and of course the on board mic.
Nothing more done than join the three short clips in 'FreeMake'.
