If you go to Adobe's website there is actually a Converter program they have (Which I myself have downloaded) that will convert from NEF to DNG which any CS application can read.
I frequent the Adobe Forums and recently asked why my CS5.5 could not read my 3200. I received information about this converter.
Evidently Adobe has a very low regard for NEF claiming its not a Standard and changes with the direction of the wind. They consider DNG as the gold standard. Adobe thinks it cost too much to maintain RAW updates for Older software when it cost just as much or more to maintain this NEF to DNG converter.
Adobe is just a contraryian outfit. Whose goal in life seems to be, tee off its customers.
