Digital SLR Camera www.bestcamerasonline.co.uk
Digital single-lens reflex cameras (also called digital SLR or DSLR) are digital cameras combining the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to either the viewfinder or the image sensor. The alternative would be to have a viewfinder with its own lens, hence the term "single lens" for this design. By using only one lens, the viewfinder presents an image that will differ imperceptibly from what is captured by the camera's sensor.
