I've used this lens for a couple of weeks now. I have used it in a variety of light. I have mainly been shooting little league baseball and basketball inside a gym. I have seen great results even with lower light in the evening (outside) and have had no issues with autofocus. I use al servo and the lens set to mode 2 and it has done a great job keeping things in perfect focus when tracking moving subjects. I was using a Canon 70-300 is usm lens prior to getting this 70-200 is usm lens and there is a big difference in the quality and capabilities of this lens. The lens is not light so I have been using a monopod and it helps. I've shot many photos zoomed to 200mm handheld and been amazed by the image stabilizer. I am very pleased with this lens. I have been able to get shots in lower light outside and inside that I would not have been able to get with my f4-5.6 lens. I am amazed at the photos that my 30d is now shooting with this lens. --- I highly recommend this lens.
