DSLR (digital single-lens reflex) cameras largely replaced film-based SLRs during the 2000s.
DSLRs are the most advanced and versatile cameras available to consumers today. They give you the most control over how your pictures are taken, and are thus meant for more serious amateur photographers and professionals. DSLRs allow you complete control over exposure settings, including aperture priority, shutter priority, and various program modes. Their fast autofocus produces great shots when shooting fast-moving subjects or scenes. They also utilize an interchangeable lens system, enabling photographers to use the most appropriate lens for whatever they are shooting. Finally, DSLRs have large sensors, which generally produce higher-quality images.
