This lens is a must when shooting outside. I use mine to shoot my kid skateboarding pools and skate parks. This lens enables you to capture a very wide scene. It also looks great when played on an HD television. It will fill the whole screen and it looks awesome. I never shoot without this lens, it is permanent unless I am shooting with a fisheye. If you are looking for a very wide scene that is not distorted then this is what you want. I found mine brand new on ebay for $420.
