WebThe focal length of a camera is the distance from the center of the lens to the focal points. If the focal points are closer to the lens center, it means the lens has more optical power to converge the light. The stronger the power, the wider field, and there is a mapping relationship between the Field of View and the focal length. WebThe actual focal length of the lens is usually measured along with the crop factor of the sensor. Cell phones, needless to say, have a huge crop factor. For example, the Samsung Galaxy SIII and iPhone 4 are a 7.6x crop. So, if you have a 5mm lens on one of those, you're looking at an equivalent full frame focal length of 38mm.
