Having debated the purchase of this lens for two years and read every review on the internet I think I must have talked myself out of this lens at least a half dozen times before I finally bought it. I must say this lens didn't waste anytime making itself one of my all time treasures. This lens is definitely designed for the photographer that uses a tripod. My biggest concern before I bought it was its size. Now that I have it, I realize it's not really any bigger than my 17-35mm zoom.
I must disagree with the previous post, this lens is definitely not a toy, nor is it a lens designed for architecture! If closeup work, stitching, and texture are important to you this is THE LENS! It is one of the finest SLR lenses you will ever put your hands on.
