The purpose of a camera lens is to focus light onto a camera's sensor or film, capturing images with clarity and detail. Lenses are designed to manipulate light in various ways, allowing photographers to achieve different effects, such as depth of field, perspective, and distortion.

Different types of lenses serve specific purposes: wide-angle lenses capture expansive scenes, telephoto lenses bring distant subjects closer, and macro lenses allow for extreme close-ups. The aperture of a lens controls the amount of light entering the camera, influencing exposure and depth of field. A wider aperture creates a shallow depth of field, blurring the background and isolating the subject, while a narrower aperture increases depth of field, keeping more of the scene in focus.

Additionally, lens quality affects image sharpness, color accuracy, and contrast. High-quality lenses minimize optical aberrations, ensuring that images are as true to life as possible. Ultimately, the lens is a crucial component in photography, shaping how we perceive and capture the world around us.
