So I'm at a dilemma here and I come to you good people of the forum. I'm looking to get either a good telephoto or macro lens. Around the price of $300, are there any good lenses out there. Being this is only my second lens for my Rebel XT (first being the standard 18-55mm) I don't think it needs to be outstanding. Now personally, I would like a macro lens but from my research I can't find anything under 500 (unless you tell me otherwise). So I figured a telephoto lens would be good for some great bird shots (I'm in an area where there's all sorts of beautiful cardinals and blue jays during the spring). I know there are other lenses besides Canon I could go with but in all honesty don't know where to begin in my search.
