DSLR stands for Digital Single Lens Reflex. It is a type of digital camera that uses a mirror to direct light from the lens to the viewfinder, allowing the user to see exactly what the lens sees and resulting in a more true-to-life image. DSLRs are known for their versatility and ability to work with an array of interchangeable lenses, making them a favorite camera choice for both pros and entry-level photographers alike. They are also capable of autofocus and can hold thousands of photos on their internal memory card. DSLRs are different from other types of cameras because they combine the optics and mechanisms of an SLR (film) camera with a digital imaging sensor.
