#REDIRECT [[Digital single-lens reflex camera]] |
|||
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]]. |

{{Redirect category shell| |

The sensor in a DSLR is typically much larger than the one in a standard [[digital camera]], which allows better image quality and shallower [[depth of field]]. 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 [[Electronic Viewfinder]]). |

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 ([[2005]]) is [[Canon EOS-20Da|Canon EOS 20Da]], a Japanese variant of [[Canon EOS-20D|Canon EOS 20D]] designed for [[astrophotography]]. |
