Definition: Telephoto refers to a lens or a digital camera with the capability to shoot photos at a closer field of view than normal human vision. Telephoto and zoom are terms often used interchangeably with digital cameras.
If the digital camera lens has a 35mm film camera equivalent measurement of more than 70mm, it is considered a telephoto, or zoom, capability. A measurement of about 50mm is considered to be similar to human vision.
