Types Of Digital Slr Cameras   by Kevin Wu

Most people currently prefer to use SLR cameras instead of the regular point and shoot cameras which have been quite handy for unprofessional photographers. Even though they are expensive, people are beginning to find them worthy especially those who value outdoor photography. If technology offers these types of SLR cameras that produces quality resulting images and as they say pictures speak a thousand words, why must one continue taking photos with his or her regular point and shoot camera?

Digital SLR cameras uses a mirror which is placed somewhere behind the lens to direct light directly at the viewfinder when a photo is being shot. When the shutter is released, the mirror slightly moves out of the way giving way to the light from the lens to go straight to the sensor where it immediately blacks out the view finder for a moment.

SLR cameras still dominate photography as far as professionalism is concerned and this is because they accommodate a wider range of lens focal lengths. That is also one of the advantages that they have over point and shoot cameras. With a Point and shoot camera, one has to match the angle of the lens that is used for viewing with the angle of the lens which takes the photos. This technique is cumbersome as it requires a complex viewfinder and this is because you will be struggling to cover a wider focal length range. This problem does not arise in SLRs as both the lenses used for viewing and taking photos are the same.

Most SLR cameras involves a technique that uses a live view mode which basically allows the camera user to make shots easily as one can do with a point and shoot or a snapshot camera. There are different types of them and some include the following:

Fixed lens digital SLR – this model uses a semi transparent mirror which is stagnant to transmit light to the viewfinder and also to the sensor at the same time. As the name suggests, the lenses on these models are fixed and cannot be removed.

The digital SLR style – this model uses an electronic viewfinder and is a standard digital camera with no mirrors. The fact that this models comes with no mirrors makes it very hard to categorize them as SLRs. They are known to use a small LCD instead of an SLR pentarism.

Interchangeable-lens full system digital SLR – this model is the dominant of the digital SLRs. It is exactly what most people know as a digital SLR. What makes them the most preferred choice is the ability to remove each of its lenses and replace them with others. Almost all the available digital SLR brands are of this type.

Interchangeable lens cameras – these types of cameras apply the same technology used in regular point and shoot cameras. The only difference is the fact that their lenses can be interchanged. These models also lack mirrors and are known to use electronic viewfinder just as the SLR style.
