I was just wondering what makes a lens good and is there a way to tell besides reading review after review? Ive been reading other threads about what lens to get and it seems people keep saying what lenses they like, but is there something that makes it better than another lens? Because I just sold a few things and have around $400 for a new lens but im not sure how to start deciding on what lens to get. If you want to suggest a lens feel free but if you can please expain what makes it better than another similar lens. By the way I am looking for a macro lens for close up nature shots.
