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 the best lens for different photography styles, such as portrait, landscape, or macro. DSLRs 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 point-and-shoot cameras, which enhances low-light performance and overall image clarity. Additionally, many DSLRs support advanced features like video recording and Wi-Fi connectivity for easy sharing.
