Hey guys, so my 17th birthday is coming up next Wednesday (14th of march) and my dad said he would gladly buy me a new lens for my D3100. However the budget us quite tight, as it being around £150 - £170 MAX. So I've already got a decent 70-300mm f.4-5.6 zoom lens but now I'm looking to get a wide angle lens. So I don't know what lens to get :s I'll be using the wide angle lens for mostly portraits and self-portraits. So help me out guys and show me a few lenses I could get with my budget. Many thanks.
