Hello, my friends asked me to photograph their daughters baptism Sunday so of course I said yes. I rented a 70-200 2.8 IS which will be my main lens along with my 24-105 3.5-4.5 and nifty fifty only if I have to use them. The camera is a rebel xt with grip and my question is do you think it is wise to use my 430ex flash with the 70-200 @ 2.8? The event won't be in a church but rather at my friends condos community room which is decently lit. Is it possible to get a shutter speed fast enough indoors with this lens to stop motion blur? I've had poor results in similar lighting with my 24-105 no flash/wide open and I'm hoping since this lens is nearly 6 times the cost it will perform better in natural light. Thanks,
Mike
