For example, a 50mm is considered standard lens for a 35mm camera, it is is considerably wider on a 6x7 camera (given it has enough coverage for the format), because the film area is much larger. Because with digital cameras with various sizes of the sensor there is no uniform relationship between the focal length and the angle of view, we need to find a way to standardize the focal length of lenses made for sensors of various sizes. For example, if the camera has a crop factor of 1.5, a 50mm lens gives you the same angle of view as a 75mm. (the image sensor size is 1/ 2.3)
