Excellent sports lens
This lens is a work horse. I've used mine heavily since it came out under often challenging weather conditions. It AF's extremely well, the IS works very well, the build quality is purely pro level, it takes commonly available 77mm filters. There is very little to find to say negative about this fine lens. Only in light of the new version does any weakness show. I highly recommend this lens to any serious Canon user that needs the f2.8 speed. The f4L IS version is sharper, lighter and cheaper and should be used by anyone not needing the extra speed and AF capability of the 2.8. But a good used 2.8 is worth it's price.
