Camera SLR an SLR camera is a camera that shows on the display the same image that will come out in the photo through a system of mirrors, eliminating Parallax error. Observed in the viewfinder image is produced by the own goal, being the framing registered identical to that observed by the photographer pictured.

For even more opinions, read materials from Kevin Ulrich. Features to difference of a camera compact, small, easy to handle, comfortable to carry and cheap, reflex camera has interchangeable lenses, heavier Viewer without error of Parallax, automatic and manual controls, higher quality image and numerous accessories, but to change, are uncomfortable to carry and are more expensive, so they are almost exclusive to professionals and amateur photographers. The main feature of the SLR camera is that the image that offers the Viewer is the same be photographed, since both come from the objective.
This eliminates the error of Parallax and preview the effect if filters are applied. The term reflex Reflex refers to the system used in SLRS to bring light to the Viewer, formed by a mobile mirror and a pentaprism in which light undergoes successive reflections. DSLR, besides the mirror viewfinder camera, has an LCD screen that initially was only used to view the photograph after firing, but currently displays in real time the image that captures the objective (live-preview), realizing the function of mirror Viewer. In this way, the cameras with LCD live-preview (like the bridge and the Micro 4/3) shared with SLR its main functionality, the image that offers the Viewer is the same that be photographed. Types there are two types of reflex camera: Reflex SLR (Single Lens Reflex, single Lens Reflex): analogue SLR camera uses 35 mm film It has Viewer mirror and pentaprism, interchangeable lenses and manual and automatic measurement and approach systems. SLR DSLR (Digital (SLR): is the digital version of the camera reflex SLR, with the difference that a sensor replaces the film.
In addition to mirror Viewer incorporates an LCD in which photography can see after firing, although some models allow its use as a viewfinder (live-preview). Regarding the sensor form factor, there are two standards: the conventional DSLR maintain the form factor 3: 2 of the 35 mm negative, while that SLR 4/3 (Four Thirds, four thirds) use a sensor with form factor 4: 3. On the other hand, there are cameras that are not reflex, since they lack the mirror Viewer, but they show on the LCD live-preview the image captured by the lens. They are halfway between a compact and an SLR camera: Bridge: not interchangeable lens. Micro 4/3 (Micro FourThirds, Micro four thirds) or EVIL (Electronic Viewfinder Interchangeable Lens): sensor Micro Four Thirds, interchangeable optics.
