The name digital SLR is short for Digital Single Lens Reflex, so named because these cameras use a mirror placed behind the camera lens to direct light toward the viewfinder when you’re composing a photo. When you release the shutter, the mirror swings quickly out of the way, letting the light from the lens move directly to the sensor and viewfinder black out momentarily. The display of an SLR incorporates a prism – usually a pentaprism – that revolves around the new image so you can see well up and bouncing on the screen is where you can see it.

The SLR design allows one camera to accommodate a wide range of lens focal lengths, and that is the biggest reason that dominate serious SLR photography. The explanation? With a non-SLR camera, you have to match the angle of vision of “making” of the lens with the “viewing” lens. That is easy with a zoom lens or a short range, but it requires increasingly complex and expensive mechanisms such as viewfinder you try to cover a wide range of focal lengths. With an SLR, you avoid this problem because the taking and viewing lens are one and the same thing.

Most models of entry-level DSLR beyond the models incorporate a Live View mode, which allows the photographer to use the LCD to compose shots the same way you can with an instant camera. The most basic implementations generally lock the mirror, the prism diverting the image to a small sensor that feeds through the LCD instead of the capture of the sensor. This tends to hurt performance, however. Earlier versions require you to focus manually when in Live View mode, but the current use of automatic models.
