Capturing amazingly sharp photos of birds is the goal of many birders. There are different ways to do this, one is super zoom cameras.
The superzoom genre of point-and-shoot cameras comes with very capable and aggressive image stabilization systems to allow for photographing at these extreme telephoto lengths.
When it comes to focusing, the superzoom might not be as fast and immediately accurate as the SLR and telephoto lens, but I have seen birding images of birds in flight that were captured as well as any other camera could. Another disadvantage of the superzooms is their relatively small maximum apertures that deliver less light than the large telephoto lenses, but they can more than make up for this shortfall by offering fantastic zoom ranges in a relatively light, compact, and inexpensive package
