What do digital camera manufacters mean by 35mm format equivalent lens?

The CCD arrays in a digital camera are much smaller than the imaging area on 35mm film.The CCD size differs from camera to camera. So in order to eliminate any confusion, the focal length is often stated by the camera manufacturer as a 35mm format equivalent, because people are more familar with the 35mm lenses and what kind of image a certain lens will often produce. In order to arrive at the 35mm format equivalent they need to multiply the size of the sensor by a value called the “focal length multiplier”. The focal length multiplier is expressed as a scale factor such as 1.5 or 1.6, thus on a digital SLR with a focal length multiplier of 1.5x, a 28mm lens would produce the equivalent picture angle, (strictly “field of view”), of a 42mm lens. The 35mm format equivalent of the lens on your camera is usually included in the specifica- tion section of your camera users guide or manual.
