Focal Length Scaling: Same sensitivity feel on different FOVs

WebOct 20, 2024 · As the focal length is increased, the “magnification” is increased at the sensor end. The net effect is spreading the light coming out of the lens to a larger diameter circle, reducing the “brightness” in proportion to the area increase. There’s only a fixed amount of light flux. WebThe focal length of a lens is a fundamental parameter that describes how strongly it focuses or diverges light. A large focal length indicates that light is bent gradually while a short focal length indicates that the light is bent at sharp angles. small clear trays for cabinets
