recommend a wider angle lens?

[MiazdaKat]

I currently have a D90 with the Nikkor 50mm 1.8, and the Nikkor 55-200 4-5.6. I'm looking to add a lens or two to my kit (less than $400 each). Obviously I'm lacking in the shorter focal lengths, so I'm looking for something there. Mainly I do portraits and landscape/architecture, any recommendations? If I was going to pick up another lens I would probably be looking into the macros...

Thanks!

Budget?

And maybe it's time to update the sig.

Take a look at the Tamron 17-50 if you want a normal-ish zoom. Ultrawide, the Tokina 11-16 is probably worth a look.

I would highly suggest the Sigma 10-20 HSM - the original version not the new one. You can pick it up used for under $400 and its a great lens and super wide.
