What Is A Dslr Camera Mean
(Digital Single 50ens Reflex) A digital still image camera that uses a single lens reflex (SLR) machinery. Most professional cameras were analog single lens reflex until digital SLRs emerged in the early 1990s. Following are the two major advantages of DSLRs.
Removable Lenses
No single lens can handle every photographic requirement, and SLR cameras have always used removable lenses. A wide diversity of lenses are available for each camera system, and many lenses that fit 35mm moving-picture show SLRs also fit DSLRs. However, the CCD or CMOS sensor in all just loftier-end DSLRs is generally not as large as a 35mm frame, and 35mm lenses produce different focal lengths (encounter crop gene). See CCD sensor and CMOS sensor.
Through the Lens
In an SLR, the photographer sees the epitome through the bodily film lens. To etch the picture, a mirror reflects the low-cal from the lens to the viewfinder. When the picture is taken, the mirror momentarily flips out of the way to permit the low-cal to pass through the lens diaphragm to the CCD or CMOS sensor (or to picture in analog SLRs). Through-the-lens viewing enables precise manual focusing. See mirrorless camera, viewfinder, digital photographic camera and 4 Thirds arrangement.
Beware the Dust!
Unlike an analog SLR, which uses a fresh moving-picture show frame for each photograph, the DSLR uses the aforementioned sensor fleck forever. Because the sensor is susceptible to dust, it is imperative to e'er keep the lens port covered when no lens is attached. Starting in 2007, DSLRs began to include automatic dust removal. A "mirror lockup" part flips the mirror out of the way to expose the sensor for cleaning, and in that location is a raft of cleaning materials on the marketplace.

Holding a DSLR
In add-on to the LCD screen, DSLRs also have viewfinders, which helps photographers hold the camera steady when pressed against the face up, especially with large lenses every bit in this example. (Image courtesy of Canon Inc., world wide web.catechism.com).
