Photography is an art that is entirely subjective and objective at the same time. If you know what you want to accomplish sometimes making the best choice possible is difficult. In shopping for a lens and reading reviews, there are always suggestions that begin to lead your focus to a broader or perhaps different perspective making lens choice so frustrating! I begin to think, "yes this is the lens I want to use," then someone makes a good point that makes you have to think about what's truly important to you. I think I'm going to have to rent a couple before I decide on a piece of equipment to invest in.
