Hi, 2 days ago I got myself the E-P1. I am not interested in manual lenses, but don't have any clue as to what lens to get or adapter, what do people mean by legacy adapter mount etc. There is a used camera store nearby, and they sell used old lenses. If I go there what should I look for, what about adapters etc. I probably need a portrait lens, a lens for low light and a tele lens. Oh! i forgot to mention that it needs to be inexpensive. My wife cleared me for teh cam, but I don't think I can get away with expensive lenses now. I have heard people talking about $20, $30 , $50 lenses. Under $100 is what I am looking for. Kindly suggest which lens and where can I find it.
