bringing this one back because i'm in the market for a 70-200 and im trying to figure out if the F2.8 is worth it over the F4. On the 17-40 i have, i wish i would have gone down to F2.8. I will be going with an IS version of the 70-200 so im wondering if the 2.8 will be necessary. I'm going to be using it for soccer outdoors at night and other sports as well. just would like some opinions
