SLRs have a different viewing system, as well. With the exception of a couple of models from Olympus and Panasonic, the design of a digital SLR makes it impossible for the sensor to feed a live image to the LCD display on the back. This means that you have to compose shots using the optical viewfinder. However, the viewfinders on digital SLRs are vastly superior to those on compact cameras and show you the view through the camera lens itself. Consequently, what you see in the viewfinder is exactly what the camera will photograph.

Digital SLRs have faster focusing systems than compact cameras, despite the fact that their lenses are physically larger and heavier. There is still some shutter lag, but it is usually far less. What’s more, you can switch to manual focusing, and the size and sharpness of the viewfinder image means that you can easily see when your subject is in or out of focus.

Digital SLRs offer manual photographic controls which are frequently missing on compact digital cameras. You have control over both the shutter speed used and the lens aperture, and this is important for many creative effects. Digital compact cameras are easy to use but ultimately limiting. SLRs offer the potential to take your photography much further.
