Slr Cameras

SLR camera is the abbreviation for Single-lens Reflex camera and it is type of camera that uses a movable mirror. The mirror is between the lens and the film and projects the picture onto the film. The same mirror image is also used to be displayed in a viewfinder to be able to exactly see the picture that will be taken by the camera. This feature that the photographer see the actual picture focused on and taken is a unique feature of the SLR camera and distinguishes SLR cameras from other cameras. This is one of the reasons why it took a certain amount of time longer to develop digital SLR cameras than any other type of digital camera.

A shutter is used to prevent light from penetrating and exposing the film in between pictures. In the mid 1970s the SLR film technology started to get sold and used more and more and is ever since then the preferred camera type by amateur and professional photographers.

In 1884 was probably the first SLR large format camera sold.

Single-lens reflex cameras have been built for several film formats. The most used SLR format is 35mm, it is a good compromise between size, quality and cost. If a higher quality picture is needed some medium format cameras can achieve this. Digital SLRs had the problem that the same picture coming from the camera lens could not be displayed on a screen. After developing new technologies it is now even possible to build digital cameras with a LCD screen displaying the actual picture. DSLR cameras came onto the market close to 2000 and are nowadays widely used by many professional photographers.

Lots of accessories are available for SLR cameras; most of these are filters and lenses. Several companies offer SLR cameras with long-range zooms, good to take pictures of far away scenes such as dangerous wildlife.

Special SLR camera bags are needed. The bag needs to have a bulk out on the front for the lens and often times space is needed for additional filters and lenses.
