Normally, the cameras which are not loaded with the SLR feature will not give the photographers the exact view of the subject which actually appears in the final photograph. But, the SLR feature helps the photographers view exactly what will be captured by the film or the digital imaging system. Before the introduction of the SLR camera which stands for single lens reflex all the classical cameras had two optical light paths. This optical light path helps capture photographs well when the subject is at a middle or longer distance. But, when it comes to close-up shot its efficiency goes low. Moreover, the cameras which are not equipped with SLR feature perform very poorly while capturing photos in low light and while using low speed films.

Till the 90s, the cameras equipped with the SLR feature were the most advanced cameras. But, the recent developments have left even the digital SLR cameras far behind. Today, the latest compact digital cameras are equipped with LCD. This helps view exactly what CCD captures. Today, such digital cameras are available at flexible prices in the market. Yet, the SLR cameras are very popular among the professionals and the amateurs because of its clarity and shadow details. The photographers can manually adjust the focus in the SLR cameras and they can also be automatically focused by the auto focus feature. It also supports matter focusing screen to diffuse the light that may spoil a photograph. Thus, these features help get exact viewing, focusing and composition.

The digital SLR cameras have a larger sensor in comparison to many other brands. This helps capture quality photographs even in low light. When the sensitivity of the camera is larger it helps increase the quality of the captured photographs. The sensitivity of the SLR camera is pretty large. The range of the digital SLR is 100 -1600 and it depicts the sensitivity of the digital SLR.

Moreover, the quality of the SLR cameras has further increased over the years. Now, this camera functions faster. The time this camera takes to capture the subject right after the click of the shutter is incredibly faster. But, typical cameras take about 0.5 seconds to complete this task. It is a pretty longer time in comparison to that of the digital SLR. Definitely, one cannot ignore the capacity of the battery as you consider the other features of the SLR digital cameras. With the capacity of the digital SLR you can capture approaching 2000 shots. Moreover, you can interchange the lenses of the digital SLR cameras.

Every thing has its own disadvantages and the digital SLR is no exception. In comparison to typical cameras the digital SLR's weight and size are more. Since, this camera does not possess LCD screen it is not possible to preview the images in this widget. To view the images in this camera it requires additional accessory. Moreover, the prises of the lenses of the SLR camera may be more than that of the camera itself.

The digital SLR cameras help the users know immediately whether the photographs they have taken are of good quality. So, it helps users take better photographs. In monetary terms as well this camera proves to be profitable as the users need not purchase rolls of films. They can just use memory cards which are reusable and can support hundreds of photographs. Moreover, the battery of this camera is rechargeable and it lasts for years if handled properly.
