I have been using this as my primary lens for about 1 1/2 years and it is really good. I have shot thousands of images and taken the lens through some tough situations. It has the best range that I have seen without sacrificing too many f-stops. You can go from wide angle to close focus in the blink of an eye. The auto-focus is pretty fast, but I did have a problem with this. My auto-focus motor broke about a year in, but it was covered under warranty. I didn't like being without the lens for the time it took to fix it though. I would still recommend it as one of the best out there.
