In which objective is the light darker brighter?

In Photography, the brightness or darkness of light can change based on the objective or lens used. Typically, a lens with a wider aperture (lower f-number) allows more light to enter, resulting in brighter images. Conversely, a lens with a smaller aperture (higher f-number) restricts light, making images darker. Additionally, the focal length can affect exposure; longer focal lengths may require adjustments to maintain brightness.
