The Canon EF 70-200mm f/4 USM L IS is an amazing lens. It is truly outstanding when used on APS-C DSLRs and it suffers only from a minor quality deteriorations on full format DSLRs. The resolution figures are easily on prime levels throughout the whole range and even at max. aperture. Unlike most other full format lenses it manages to keep the vignetting on a moderate level.

The Canon 70-200mm f/4 L IS is as perfect a zoom lens as I have ever used, and its ergonomics are also first-rate, never getting in the way of a great photograph. I wish all telephoto zooms focused more closely, to about 1.5' (0.5m) instead of 4' (1.2m), but no similar high performance zoom does any better.

For many, many other general-purpose tele-zoom needs, the Canon EF 70-200mm f/4.0 L IS USM Lens will be a great solution. For shooting at the park (public park, ball park, water park, ...) the beach, the vacation rental house, or just out in the back yard, this is a great lens to have in the kit.
