Yes, there are different camera lens' for different cameras. Not all cameras have different camera lens' though and that is because they have an automatic focus.

Bridge cameras often lack some of the functions of their single-lens alternatives such as a viewfinder and interchangeable lens. They can be purchased at photographic specialist stores as well as online retailers such as Amazon.
