SLR cameras are among the most advanced photographic equipment. They are especially suitable for advanced amateurs and professionals who place high demands on image quality. SLRs use an optical viewfinder that captures the image reflected from the lens. As a result, the scene you get in the viewfinder is without distortion.
Digital SLR cameras enable you to take photographs of the highest quality. They are suitable for enthusiastic amateur and professional photographers. DSLR stands for Digital Single Lens Reflex and is usually used when referring to digital SLRs.
