How do convex lenses enhance the functionality of a camera?

Convex lenses enhance a camera’s functionality through their ability to focus light on a specific point, which is crucial for capturing sharp and clear images. When combined with other optical components, convex lenses can help control the light’s path, allowing for adjustments in aperture and depth of field. This feature enables photographers to create a range of artistic effects, like blurring backgrounds while keeping the subject in focus. Additionally, the design of convex lenses plays a key role in minimizing distortions, ultimately leading to higher-quality images.
