Hey guys, as im out in the states atm in nyc i thought i'd look to grab a decent lens other than the stock 55mm one that came with it (nikon d3100). Any nice recommendations for something decent that wont break the bank yet be an improvement on the current lens? I would usually spend a few days researching but its going to be a bit of an impulse buy as I only have mobile tinternetz- i know some of you guys have some great knowledge here though
