Hello folks, I am new to this forum. I glad to be here! After careful consideration, I decided to get a lens for MACRO work but that is also good for nice PORTRAIT photography. This may be the best way for me to get started with a Nikon D90 and the type of photography I want to do. I am on a budget, so I am hoping that I can accomplish this with about $300 - $400 for the lens. Is that possible? What are your best suggestions? Thanks!
