SLR stands for single lens reflex. What it means in practice is that you, the photographer, sees exactly what the lens sees. It also means you can change the lens, that the camera has large image sensors that produce high-quality photos with minimal lag time, making them ideal for action photography.

 

Digital SLR cameras, although less common than compact digital cameras, were up until 2005 used mainly by professionals. Now, they are finding their way into the consumer market because prices are falling low enough for them to be able to compete with high end compact cameras. .
