i've been searching through all the forums trying to find an answer to my question, but to no avail. so i'll just ask I've been getting into macrophotography lately, but it's not very easy with the standard 18-55mm lens i have. I would love to be able to buy a nice macro lens, but i'm in college and so money is hard to come by. Is there anything else I would be able to use to help me get some good results? Would an extension tube help? Or maybe a close up filter?
