The Sigma 30mm f1.4 is an odd lens... it has good center sharpness, but its edges are beyond soft!
The Nikon 35mm f2 is a better lens, and cheaper at that. And a lot lighter too.

Another affordable option is the Nikon 24mm f2.8... but I do not see the point of this lens, you have the same or better quality 24mm in your Sigma 18-50 f2.8 already, at the same max. aperture.

So... seen in the light of that you already have a good wide angle zoom, my guess is you are looking for a biggr max. aperture than f2.8...

A very nice lens is the Nikon 28mm f1.4 D. Very nice optically, but not in production anymore. If you find it 2nd hand, a really nice lens to have.

Another out of production lens from Nikon: The 35mm f1.5 Ai-S.
Good when stopped down to f4 or so... otherwise soft into the corners and vignets heavily wide open, better save money and get the AF-ing, better, 35mm f2.

I think those are the options, there are not many fast wide primes from nikon.

If I had a Nikon DSLR, I'd look at the 35mm f2 and 28mm f1.4. The f2.8 primes do not perform better than your 18-50 f2.8 Sigma, they actually perform worse in areas.

you are right, must be a miniumim of f2 for me to consider. preferabley under.
is the sigma's edge softness as bad even stopped down ? i don't mind soft edges wide open. i might have a look on the bay for the 28mm.

Lord. I just sold a 28mm (although that was f2.8).

I have the 35mm f2 and its brilliant. fantastic sharpness and great photo quality. I was amazed at how i could tell (from my holiday in Rome) when i used that lens from the Photo quality.

I did a rough and ready (read non technical, camera on a table) test between the 28mm and 35mm when i had it.

$4300 for a 28mm f1.4 lens ? the same price as a d2X. bloody ridiculous.

Rooz, I do not know another lens that gives such inconsistent reviews and results as the Sigma 30mm f1.4. Some love it (photodo), some have serious issues with its focussing (ken nikonian), some see corner softness to quite some degree (photozone) and some rated it the same as the Nikon 35mm f2 (ColorFoto)...

This makes me believe that 1. it is not accurate in AF, and 2. its focal plane is curved into the corners.

Here is an interesting, yet confusing, "comparison":
http://www.pbase.com/miljenko/sigma30

About the yes/no in soft edges, since it seems to be a fault of the focal plane, it will matter less in "3D" real world photos, than when you shoot something that is in a flat focal plane... so depending on the subject, it might not be a problem for you. Do check the AF accuracy of the sample you are about to buy though, on a D200 it seems to be unreliable (according to link above, ken whathisname's review).

Confusing lens... do note its moderate barrel distortion depending on what you want to use it for.

There are two other Sigma wide lenses that are in a way intriguing too:
The Sigma 24mm f1.8, vignets a lot less than the 30mm f1.4, a tad less center sharpness, a tad less distortion, a bit less contrasty. And quite a bit wider.

The Sigma 28mm f1.8. It vignets quite a bit less than the 30mm f1.4, especially when stopped down there is no light fall off into the edges. About the same sharpness, same contrast, and about half the barrel distortion. You gain 2mm wide, lose 0.5 f-stop, and may lose the AF inaccuracy, since it uses your D80's AF motor.

Uhmmm WOAH. I know I said it is a good lens... but that good, for such 2nd hand prices?!

I didn't know it would be that rare, thats close to the prices the very rare Canon 50mm f1 L fetches!
