Choose my next lens

I am willing to spend roughly $250-350 on my next lens...

I use a D90 body and own an 18-55mm and 70-300mm lens.

What should I put next in my quiver?

18-70mm - http://www.nikonusa.com/Nikon-Produ...X-Zoom-NIKKOR-18-70mm-f%2F3.5-4.5G-IF-ED.html (this one is a little out of my price range but I would sell my 18-55mm probably)

35mm - http://www.nikonusa.com/Nikon-Products/Product/Camera-Lenses/2183/AF-S-DX-NIKKOR-35mm-f%2F1.8G.html

Open to suggestions? Pros/Cons, Advantages to each.

 

I got the Sigma 18-200 on my D90. It is a GREAT quality lens. It gives you wide angle and zoom in a single lens with image stability!! Now I don't have to swap lenses!

Here is a 4 or 5 page review.

Oh .... This lens is about $575 in Canada so a bit cheaper in the USA probably. Great deal!!! Excellent quality ... I believe that it's more durable than the Nikon lenses.

Cheers.

 

Out of the 2 I. Would get the 35 but I would really just save and get the 50mm 1.4

 

Can you explain why? I'm not to up on my tech

Can I use a FX format lens?

What is the difference between these two?

why would you get the 18-70? its almost like the kit len

 

Primes for the win!

If you are not using a full frame camera I would get the 35. If full frame get a 50
