Camera reflex A camera reflex is a camera that shows in the viewfinder the same image that is going to appear in the photo by means of a system of mirrors, eliminating the parallax error. The image observed in the viewfinder is produced by the own objective, being the frame registered in the identical photography to the observed one by the photographer.

Characteristics Unlike a compact camera, small, simple to handle, comfortable to take and sale, the camera reflex counts on interchangeable optical, viewfinder without parallax error, automatic controls and manuals, major quality of image and numerous accessories, but in return they weigh more, they are uncomfortable to take and they are more expensive, reason why they are almost exclusive of professionals and photographers amateur. The main characteristic of the camera reflex is that the image that offers the viewfinder is the same that is going away to photograph, since the two come from the objective. This it allows to eliminate the parallax error and to previsualize the effect if filters are applied.
The Reflex term The term reflex makes reference to the system used in the SLR to make arrive the light at the viewfinder, formed by a movable mirror and pentaprisma in which the light undergoes successive reflections. The digital camera reflex, besides the mirror viewfinder, counts on a screen LCD that initially was only used to visualize the photography after the firing, but at the moment shows in real time the image that catches the objective (live-preview), realising the function of the mirror viewfinder. This way, the cameras with screen LCD live-preview (as bridge and Micro the 4/3) share with reflex their main functionality, that the image that offers the viewfinder is the same that is going away to photograph. Types Two types of camera reflex exist: Reflex SLR (Single Lens Reflex, unique Reflex of lens): analogical camera reflex, uses film of 35 mm Has viewfinder of mirror and pentaprisma, optical interchangeable and systems of measurement and approach automatic manuals and. Reflex DSLR (Digital SLR): reflex SLR is the digital version of the camera, with the difference of which a sensor replaces the film.
Besides the mirror viewfinder they incorporate a screen LCD in which the photography can be seen after the firing, although some models allow their use like viewfinder (live-preview). With respect to the form factor of the sensor, two standards exist: the conventional DSLR maintain the form factor 3:2 of the negative of 35 mm, whereas reflex 4/3 (Four Thirds, Four Thirds) uses a sensor with form factor 4:3. On the other hand, cameras exist that are not reflex, since they lack the mirror viewfinder, but show in screen LCD live-preview the image caught by the objective. They are halfway between one compact and one camera reflex: Bridge: noninterchangeable objective. Micro 4/3 (Micro Four Thirds, Micro Four Thirds) or EVIL (Electronic Viewfinder Interchangeable Lens): sensor Four Thirds, interchangeable optics.
