Welcome..., to the Machine!


I would say 2 lenses are better than one. Keep the 18-55 Kit Lens for family shots and walking around and I really like Daniel's suggestion of the 70-200mm f/4L for $640 for your kids sports, and it's also a good portrait lens.


I don't think you will have to bring 2 lenses to football games, the 70-200 should handle all of that. This will be a very good outdoor sports lens, but it's too slow for basketball indoors in poorly lit gyms. If you decide you want longer reach for football then you could always add a 1.4X extender ($300) and then the lens will be 98-280mm f/5.6L, which will be fine if there's plenty of light.
