Digital single-lens reflex (DSLR, or digital SLR) cameras (FIGURE 1.1) are the performance standard in today’s photography market. Characteristically, DSLR cameras for the most part offer excellent image quality, have large sensors that work well in poor lighting conditions, start up quickly when turned on, and have high-performance autofocus systems, short shutter delay, fast continuous shooting, and greater flexibility and versatility for creative photography.
