Digital Single-Lens Reflex Cameras, often abbreviated as DSLRs, are a type of digital camera that uses a mirror mechanism to reflect light from the camera's lens up into 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 the best lens for different photography styles. DSLRs are popular among both amateur and professional photographers due to their versatility and image quality. They often feature larger sensors than compact cameras, which can result in better low-light performance and depth of field control. Additionally, many DSLRs come with advanced settings and manual controls, allowing for greater creative expression.
