Canon 70-200mm f/2.8L IS or non IS?

Hi everybody!

I am considering buying a 70-200mm f/2.8 lens for my Canon T1i and am wondering if I should spend the extra money for the IS version. I take picture of the kids and their sports such as soccer, swimmong, gymnastics, etc. I will also be taking pictures of surfing once in a while. My lens budget is tight so I don't want to spent the money for the IS version if I'm not going to need it.

Any insight or experience is greatly appreciated.

Sorry for all of the posts...I'm having problems with my internet connection and didn't realize that the two previous posts had sent. My first post on here and I already look like a dummy...great!

If most/all your work is going to involve fast shutterspeeds (ie 1/400+) then dont bother with the IS: it wont help any.

If you do "panning shots" the IS would be helpfull. I shoot motorsports, kids, sports, kids playing sports and I opted for the IS version...love it! The IS would also be helpfull if you are going to shoot things other than action...low light shots, portraits and/or candids, etc. Do some searching on yahoo or google on IS vs non IS, you might find more helpfull information.

Maybe these will help?...
