-A '''digital single lens reflex''' or DSLR camera is a [[single-lens reflex camera]] (SLR) which records images using electronic sensor instead of [[photographic film|film]]. Like SLRs, DSLRs are often used by professional photographers and advanced amateurs.

-DSLR accepts interchangeable lenses and accessories such as flash units, and accessories for SLRs are usually compatible with DSLRs of the same brand. When aiming a DSLR, the photographer is looking through the lens (unlike a [[rangefinder camera]] or a camera with a separate [[viewfinder]]) and the image is projected optically (unlike a camera with an [[Electronic Viewfinder|electronic viewfinder]]).

-The sensor in a DSLR is typically much larger than the one in a standard [[digital camera]]. Larger sensor allows better image quality, shallower [[depth of field]] and wider [[field of view]]. However, the sensor is usually smaller than a frame of [[135 film]]. If this not the case and the sensor is 35 mm wide, the camera is said to have a ''full-frame sensor''. Currently ([[2005]]) only expensive professional DSLRs have full-frame sensors.

-Depending on the position of the reflex mirror, the light from the scene can only reach either the [[eyepiece]] or the sensor. Also, a mechanical [[shutter]] is used to control the [[exposure]]. Therefore even though a DSLR has a color display at the back of the [[camera body]], it doesn't provide "live preview" (allowing [[focusing]] and [[framing]] using the display). The only exception to this rule so far is [[Canon EOS-20Da|Canon EOS 20Da]], a Japanese variant of [[Canon EOS-20D|Canon EOS 20D]] designed for [[astrophotography]].
-Camera manufacturers expect that professionals and advanced amateurs continue to prefer DSLRs over other forms of digitals cameras. However, if electronic viewfinders with near-zero lag are introduced, non-SLR cameras will become a viable choice for a large number of people who now need SLRs.
