Digital Single Lens Reflex camera -- a digital camera that uses mirrors and a pentaprisim (or pentamirror) so that the optical viewfinder looks out through the camera lens. DSLRs are characterized by having interchangeable lenses and generally more professional features than point-and-shoot cameras, such as better autofocus, less noisy images in low light, and faster frame rates.
