Wow, had the opportunity to get the IS version and turned it down?? My opinion is to always go with the IS since you never know when your going to need it, but that's just me. I had the non-IS 70-200 f4 and traded it in for the IS version after about a year and I can tell you that the IS has saved many a shot for me.


I think all copies in the 70-200 series are excellent and I'm sure your going to get some really nice shots with that lens. I do a lot of indoor shooting so I've been thinking of upgrading to the 2.8 IS version but I also plan on upgrading to the 5Dmk2 in the next couple of months so I don't know if that will be entirely necessary.


At this point, it sounds like a moot point for you anyway if it would be a big hassle to ship the lens back and get the IS version (to pay yet another shipping fee) I would just use your lens until you reach a point that you find yourself encountering a lot of shooting situations where you need the IS.


Happy shooting!
