Final answer:
Focal length and field of view differentiate one camera from another.
Step-by-step explanation:
Focal length and field of view are what differentiate one camera from another.
In a camera, the focal length determines the magnification and the field of view. A shorter focal length results in a wider field of view, while a longer focal length results in a narrower field of view. For example, a wide-angle lens has a short focal length and captures a wider scene, while a telephoto lens has a long focal length and captures a narrow field of view.
