first is HB and second is d700, you can see the crop differences so it's an easy one.
Skin tones are better in the HB, there is also this glow on the skin the D700 does not have.
I would not know how to get that in post process and how long this takes.
Is it worth buying a HB? Currently I have the D700, here used with the very best glass(85mm 1.4g) which I don't have in other dimensions (50,35 or 24-70 are not on same level).
