Okay this is my first "L". Man I did not know how much I was missing. It was hard to decide between this and the 24-70 f/2.8. After a lot of research, comparing, feeling, etc, IS range and weight won.
And this(pic below) is using my "L", 1/10sec ISO 800 without flash in a moderate lit living room at night, f/4.0
