I use NX1 to work on the raws from my D200. I downloaded a sample NEF taken with a D700 from the internet. It does not open in my copy of NX(Version 1.2), i've read you need NX2.
Which raises the question, if the D3 (Whose NEFs open in NX1.2) and the D700 share the same sensor, why is different software required to work on the D700 NEFs? Is it just a flag set somewhere?
I dont have a problem upgrading to NX2 when the D700 comes out (If it isnt already included in the box). But i wonder if Nikon will update NX1.X to include D700 support.. bit cheeky if not, as the D3 would suggest NX1 to be capable.... unless of course the cameras are not as similar as we've believed.
