A DSLR camera is the abbreviation for digital single-lens reflex camera that uses an automatic mirror system and pentaprism or pentamirror to direct light from the lens through the viewfinder eyepiece.

The basic operation of a DSLR is for viewing purposes. Basically, the mirror reflects the light coming through the attached lens upwards at an approximately 90 degree angle. It is then reflected by the pentaprism to the photographer's eye. During exposure that is during a photograph is bring taken, the mirror swings upwards and opens the shutter to allow the lens to project light onto the image sensor.

Interchangeable lenses for DSLRs are built to operate correctly with a specific lens mount that is generally unique to each brand. Photographers often use lenses made by the same manufacturer as the camera body although there are also many other independent lens manufacturers that make lenses for a variety of different lens mounts.

The fact about DSLRs is that any DSLRs would produce a blurred image if there's no lighting. Images produced during the night would often be not clear or may have less pixels. However, a DSLR in another hand, produced high quality pixels during the day. Besides, the optical zoom of a DSLR would again be better than a digital camera.
