58mm? What? Maybe learn a little more. Then get into really wide angle stuff. Cause more than likely, you will be getting some interesting results with the wide angle cause it does take practice to learn how to use it due to how wide they can get and you can seriously make shots look horrible, very quickly. You have to learn how to stand and angle yourself properly to make a really wide angle lens work for each picture.

Majority of the time though, look at Sigma 10-20's, Tokina and Tamron have decent ones, but they will all get up in the near $600 range lately for the newer models.

Just go to ww.bhphotovideo.com and search sigma/tamron/tokina wide angle...
