DSLRs offer several lens choices.
DSLR stands for "digital single lens reflex." It is an acronym conveying how the camera works and that it only uses one lens compared with point-and-shoot cameras.
How it Works
A small mirror inside the camera behind the lens reflects the light of the object through the lens and to the eye of the photographer. In other cameras, the photographer looks through a viewfinder. When the shutter is pressed, the mirror flips up and the image is recorded.
Benefits
The photographer actually sees what she is photographing and what will be recorded, as opposed to looking through another lens (viewfinder) slightly above the camera's lens. He is seeing exactly what he is shooting, including the focus, lighting and colors.
Additional Benefits Over Point-and-Shoot Models
Digital SLR cameras have interchangeable lenses and multiple other accessories such as flashes that can light subjects at a much greater distance than the 10 to 15 feet that point-and-shoot flashes allow. Manual settings are also more advanced on SLRs than on their point-and-shoot counterparts.
