What will happen when focal length increases or decreases |
|
Answer» ong>Explanation: iAs the focal LENGTH VALUE decreases, the lens BECOMES a wide-angle lens, and as the value increases it becomes a telephoto lens. The brightness of a lens is decided by a combination of focal length and lens DIAMETER. If the focal length of two LENSES is the same, the lens with the larger diameter will be brighter. |
