I think 5.2mm f1.4 on 1/1.7 sensor should be 16mm f4.5 on nx.

Would it be approximately correct to say that the Ex2f at f1.4 would give a DOF equal to f4.5 when compared to NX? Noise at low light would then be greater as well because of less available light. However, required ISO and shutter speeds would be based on the f1.4 rather than the f4.5 equivalent? So you could use a faster shutter speed in low light as compared to a NX with same ISO setting with aperture set at f4.5 on a 16mm focal length?The advantage of this f1.4 would be less motion blur and the disadvantage would be more noise and a greater DOF?

If you're using the same iso, then yes, but nothing says you have to use the same iso and they won't be equivalent photos if you are.
