Lenses

The lens is an essential part of any digital camera. While shooting subjects, lenses focus light onto a sensor and allow the adjustment of focal length to zoom in or out of the subject.

The amount of light that passes through the lens is controlled by the aperture. Compared to most compact cameras, digital SLRs use interchangeable lenses. They are selected on the basis of specific conditions, or during shooting to suit the requirements of the photographer.

Lenses are classified by type, focal length and specialization.
