Nikon d700 or Nikond750 or Nikon d7200 (1 Viewer)

Hi I currently have a Nikon d5300 and a vintage canon 400mm prime lens. I want to change my actual camera and I'm considering the Nikon d700 or Nikon d750 or Nikon d7200.
I was thrilled with the d700 but I'm not sure if the 12mp will give too little space for cropping. The Nikon d750 has more mp and video but lacks the reputation of the d700. I've found more people using the d7200 due the cropping factor of dx sensor.
I'm into manual focus vintage lenses, and I've read that the d700 has a rangefinder to assist the manual focus.
Any advise about which camera choose?

Both D700 and D750 are full frame bodies and you will "loose" reach compared to the D5300 as your 400mm lens becomes a 400 mm lens.
OF the two I would go with the D750 as the D700 is as least two generations older, not only in terms of sensor resolution but also in High ISO performance that is always an issue when shooting moving subjects.
I guess the question you will have to answer for yourself is FX or DX. If DX is the answer I would also look into the D500.
