I just did a test with both. At f4 and above they take almost the same image. Buy the Sigma unless you make a living with your camera. Below f4 (which is the only reason you buy either of these lenses) the Sigma takes a significantly inferior image. No big deal uless you crop in where you find the Sigma image is unusable.
