WebIf you hold all the other factors constant, the difference between the weight and size of a 24mm unit compared to that of a 50mm unit would be the barrel length. Focal length is the physical distance from the center of the optics to the sensor. Since this distance can't be on its own, it's enclosed in a lens barrel. WebThe distance from the lens to the focal point is called the focal length. For converging lenses, the focal length is always positive, while diverging lenses always have negative focal lengths. However, these conventions are arbitrary, and physicists could just as easily have made the signs opposite.
