According to Canon the EF 70-200 f/2.8L IS focuses twice as fast as the non -IS: http://www.canon.com/camera-museum/tech/report/200109/report.html#t4 . "Feature 3: Silent, high-speed AF. The AF performance of the EF70-200mm f/2.8L IS USM is up to about twice as fast as that of the EF70-200mm f/2.8L USM by improving the AF drive circuits and AF algorithm of the ring USM drive and inner focus design."
Has anybody tried/owned both and found this to be true? I'm going to purchase one of these for use with my 40D to shoot my grandson's baseball, soccer, and granddaughter's dance performances. I'll be using the lens 90% of the time for the action shots and 10% of the time for indoor church services. I know the IS lens would be useful for the indoor church shots if I didn't want to use a monopod or tri-pod. But if the AF is really twice as fast as the non-IS, then the IS version might be worth the extra $550 for action sports and dance performances. What do you all think?
