She was using a 15-85mm F/3.5 - F/5.6
Not the best lens for action shots but love her results, especially for a first attempt.
I normally use a 70-200m for action shots and the difference in focusing speed is just insane. Having a constant aperture helps as well. She mainly kept at 85mm at f/5.6 but 5.6 just wasn't letting enough light in for the most part as well as being slow when using ai servo.
