Hello,

One of my mates wants to upgrade from the standard 18-55mm zoom on his Nikon D40. He has around £200 to £250 to spend and does not mind buying a used lens.

He does want to go wider so I was thinking of a Sigma 10-20mm or Tamron 11-18mm?? Which is better and are there any alternatives in the same price range??

thanks
