EFFECTIVE (or EQUIVALENT) FOCAL LENGTH Describes the focal length of a digital camera s lens as if it was being used on a full-frame 35 mm camera. Most but not all digital cameras are equipped with sensors smaller than the image area of 35mm film, therefore requiring correspondingly shorter focal lengths to capture a given angle of view. (See Using 35mm SLR lenses on dSLR camera bodies.)
