WebDec 23, 2024 · Focal length is the distance from the lens’s rear nodal point to the image plane inside the camera body. The greater the focal length, the greater the magnification of the lens will be. For example, a popular telephoto lens is the Nikon AF-S NIKKOR 300mm f/4E PF ED VR lens. The 300mm represents the focal length, not the objective diameter. WebJul 19, 2006 · The focal ratio (also called f/number, that is, the focal length divided by the aperture) has nothing to do with it. The f/number does affect a telescope’s magnification (with a given eyepiece), and the magnification determines the surface brightness of the view: the amount of light per square arcminute as presented to your eye.
