I had one for a while for work did not get on with the menus and preferred the D3 series layout. I don’t recall the colours being any different to the standard output of a Nikon dSLR, but then I always shoot raw files and don’t take a lot of notice of the way the previews are rendered.
We switched to D850s for the macroscopes and only shoot tethered. The D700 was given to Blanka who was on the forum for a while.
