Hello everyone, I've been taking pictures with my Nikon D70, using the standard 18-70mm lens. I've been looking for a macro lens for a while now. I'm not into sports photography, but wouldn't mind trying it out.I just need a little more then the 18-70. I looked into the nikon 18-135, but i just don't know. I am still a student so money is an issue. I went to ritz camera and tried out the nikon 55-200 and the quantaray 70-300. Both were under $200. I wouldn't mind saving up a little longer to get something in the $300-400 range, but is it really worth it now? should i just get the cheaper lens and test it out, or should i just go big now and learn later. Should i look into used lenses? thanks again!
