Combining lenses like the (new or fairly new) 18-35/3.5-4.5, 24-85/3.5-4.5, the 28/1.8, the 50/1.8, and the 85/1.8 with a D600 produces a (potential) kit which is hard to beat for any roughly equivalent DX kit, both in terms of actual price and in terms of photographic usefulness.

The only lens that you can;t replicate in the above list is the 28 1.8; wide angle primes is the one area DX will fall short on every time.

But considering that the 35 f/1.8 and 50 f/1.8 replace (roughly) the 50 & 85, and any (cheaper) DX kit lens will replace the 24-85, and that there are a number of very strong wide-to-ultra options for DX (Tokina 11-16 or 12-24, Nikon 12-24 and 10-24), with the Tokinas costing a good bit less than the new Nikkor wide angle, I think you can assemble a low-price DX kit for less money than you can an equivalent DX kit.

Assuming, of course, that you're willing to forgo the fast wide angle prime. And that's always been the sore spot now, hasn't it?

Well, then factor in things like DOF control and light gathering (of a FX sensor) in the equation and the DX option has noticeable less performance for the same money. And aside from light gathering and DOF control, the lens on a 24 MP DX camera need to deliver 1.5 times higher resolution then a lens on a 24 MP FX camera to produce similar output resolution.

So no, any f3.5-5.6 kit zoom on a DX sensor will not offer a similiar performance as the 24-85/3.5-4.5 does on a FX sensor. For that you will need to buy a more expensive DX lens, like a AF-S 17-55/2.8. The same principle applies for DX wide angle zoom compared to the 18-35/3.5-4.5.

But that is the whole point, FX is more expensive but you get also better capabilities. If you could duplicate the capabilities of FX completely with DX, there would be no point in going FX (yes there other things like base ISO performance, larger viewfinder).

Put another way, there are no FX equivalents to the 'slow' DX wide-angle zooms, nor to the slow kit zooms (or even the 'slow' 16-85 mm).
