Hey everyone! I'm dating a wonderful girl who is going to school for professional photography. Her birthday is coming up and I want to surprise her with a macro lens. I myself know how to take a decent photo, but I'm completely new to buying cameras or other equipment. She has a Nikon D610, and any recommendations or advice is greatly appreciated.

Aside from the request, I'm gonna open the thread up to a general discussion about macro and/or telephoto lenses: pros and cons, favorites, stories, etc.. Pictures of either extreme are encouraged. I don't own a macro lens, so my pic's as close as I can get while maintaining quality.
