I see that 3rd party lens makers are beating out Nikon with fast wide angle DX lenses. There is the Sigma 18-35mm F1.8, and now I see on Nikon Rumors that Samyang has a manual focus 16mm f2.0 lens soon to be out. I am disappointed with Nikon's lack of offerings in fast DX wide angle lenses.
Nikon has not shown the DX community much love. Even the 80 Millionth Lens Anniversary notice specifically praised mostly FX and CX (!!) formats. It's good that the third-party community is filling in the gaps.
I just picked up a 35mm f1.8 and I love it... But it's just not wide enough!! If there was an equivalent prime lens somewhere between 18mm - 24mm, my D5100 would never leave my side. And my D200 might get dusted off occasionally too...!
Isn't the lack of such a product dictated, in part at least, by the limitations of the DX format itself? In general, I wish there were more DX scaled fixed prime lenses. But I know that Nikon wants to concentrate marketing, and profit, into FX.
Not sure that the DX format is limiting the creation of fast wide primes. Clearly with the 16-85mm DX VR AFS, a 24mm equivalent is not inconceivable. It's simply a matter of engineering. No, Nikon is just pushing everyone to FX, but that's not the answer for everyone. The manufacturing of the sensors still haven't achieved the economies of scale with FX to get to the point where we have true D3xxx type entry level cameras at the requisite cost. That's probably another 5-7 years down the road.
