A digital single-lens reflex (DSLR) camera is a type of digital camera that uses a mirror mechanism to reflect light from the lens to an optical viewfinder. This allows photographers to see exactly what the lens sees, providing a more accurate framing of the shot. DSLRs typically offer interchangeable lenses, enabling users to choose different lenses for various photography styles. DSLR cameras are known for their high image quality, fast autofocus, and manual controls, making them popular among both amateur and professional photographers. They often feature larger sensors compared to compact cameras, which enhances low-light performance and overall image detail.
