I think that both Albert and Steve hit the nail on the head: FX allows 60 years worth of lenses to be used that way they were designed. I have the obvious bias that I've been shooting with some of these focal lengths — the 105, the 85, and the usual wides — for forty years, but that's my point: they work on FX the way they did on a 35mm film body — the way Nikon designed them.
That's not to say that state-of-the-art DX lens design is not excellent. But all things being equal — and DOF control critical for many shots — the DX crop really changes the game and crimps a shooter's style.
I just love having my 105 and 85 back where they ”belong.“
