I think that model has only been out for a few weeks. You may need to use Nikon software to convert NEF to TIFF as the next Adobe Camera Raw update for LR CC & LR6 is likely to be another two to three months away.
Have been doing that but not a big fan of Nikon's software. Guess I'll have to shoot jpeg's for the time being!
Good question. I've been waiting eagerly myself.
Will it make the next update, Adobe?
Need a fix for NEF J5 asap.
