One quick suggestion. I had the 70-200. It was nice. But it didn't quite have the pop I had seen when I had rented the is ii. I ended up selling the 70-200 and getting the 70-200 is ii. It was worth and I am glad I did especially since I got focal and learned to afma. It a more versatile lens. If your saying you would use it all the time in my opinion get the lens you will have for the next 15 years and will meet the needs of any environment. Turn off the is and your back to a better sharper 2.8.
