<p>I am new to macro photography and am really enjoying it. However, I do not have a lot of money to dump into equipment at the moment. I want to take detailed macro photos extremely close up (forgive me if I'm not using the appropriate terms, as I mentioned, I am new to this). For example, I want to be able to photgraph the details of an object (ie the point of a ball point pen or images in a water droplet). Can anyone suggest a good lens for this type of photography? I'm looking to spend under $500 (the more under the better :-) ) I have a Nikon D3100.<br> thanks so much!</p>
