A DSLR or a digital single lens reflex camera refers to a digital camera that uses a digital sensor coupled up with a single-lens reflex to produce images unlike the traditional single lens reflex camera which uses photographic film to produce images. A DSLR camera works through reflex action of a mirror which either sends the image to the viewfinder or the image sensor at the back of the camera.

This is cheaper than having a lens for the view finder and one for the image sensor which would be the case if the camera didn’t have a single lens reflex. It also bring about consistency of the image seen on the view finder which is almost similar to that produced by the camera’s image sensor.

The DSLR camera was invented as an upgrade of the more traditional SLR cameras which produced images on photographic film. Study has shown that DSLR are still the most widely used interchange lens cameras in the market today though the mirrorless camera are giving DSLRs a run for their money.

Types of DSLRs

DSLR comes equipped with digital sensors of varying size. The cameras with the largest sensors are called medium format cameras. They are fitted with a digital back instead of photographic film and are very expensive to buy due to the high cost of producing this sensors. They have the most pixels per inch ration and are used to produce images for very large prints.

The next category is the full frame cameras which come equipped with a sensor the equivalent to the size of a standard 35mm film. Full frame cameras are cheaper than medium format cameras.

. They produce high quality images and many professionals use full frame cameras for their work. With such large sensors, images produced by full frame cameras can be used printed on large prints without losing details and clarity.

Nowadays, manufactures are producing cameras with smaller sensors than the standard 35mm sensor size which has been the photographic standard for many years. Such cameras use cropped sensors referred to as APS-C. These sensors are 40% the size of a full frame DSLR sensor. These cameras are cheaper than full frame cameras and produce lower quality images than that of full frame cameras. Leica also has their own sensors referred to as S-system and are about 56% larger than full frame sensors.

Some features

One main feature of the DSLR is the interchangeable lenses system unlike in other cameras. This means that photographers have the freedom to choose which lens they want to use for different tasks. Lenses are commonly referred to as glass because their optical components are made from glass. Most lenses are manufacturer dependent and work on specific cameras. Many brands produce their own lenses that work with their DSLR cameras although there are other independent makers of lenses for different camera brands.

DSLR lenses are crucial for controlling a picture’s depth of field which determines the overall sharpness of an image. These lenses use aperture to control the depth of field by controlling the amount of light hitting the camera sensor.

You will really enoy your new DSLR, since there are so many things you can do with your DSLR.
