This, a general purpose, take-a-picture-anywhere type of lens has image stabilization, the number one thing you want to look for in interchangeable lenses of the dSLR cameras.
What I like about this lens is that it offers image stabilization. Pictures taken with full-frame sensors cameras are susceptible to blur, even when the pictures have been taken during the day. The image stabilization in the lens can reduce blur significantly. I like the way Bob Atkins describes it: "Image Stabilizer (IS) dramatically reduces image blur caused by camera shake. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane. The 3 stop advantage means that photographers normally shooting a 105mm lens handheld at 1/125 sec can obtain a shake free result with a shutter speed as low as 1/15 sec, for vastly extended options in low light conditions."
