Final answer:
A fixed-focus camera has a lens with a preset focal length that focuses well on objects within a specific distance, typically around 3 to 5 feet. Objects closer or farther away from this distance may appear blurry.
Step-by-step explanation:
A camera with a lens with a preset focal length that focuses well on objects within a specific distance is called a fixed-focus camera. These cameras are commonly found in point-and-shoot cameras or disposable cameras. The lens in a fixed-focus camera is set to a specific distance, usually around 3 to 5 feet, which allows objects within that range to be in focus. Objects closer or farther away from that distance may appear blurry.
