Input:
I love EF 70-200 f/4L USM Telephoto Zoom lens. The price is right, super quality of pictures in color and contrast. It is light weight about 1.5 pounds in comparing with its siblings, 70-200 f/2.8 with or without IS (about 3.5 pounds).

I am think about to buy the new model 70-200 f/4L with IS. With IS, I can take pictures in lower light conditions, which I could not do it with my 70-200 f/4L.
