You will be getting a great lens. I've had the 70-200mm f/4 non-IS since 2006 and love the quality it gives. Even though I have since bought the 70-200mm f/2.8 IS theoretically rendering the f/4 lens redundant, I have never felt the desire to sell my older lens and still use it, judging the IQ as good as the more expensive lens. It's also a lot lighter to carry on landscape expeditions.
