A Single Lens Reflex (SLR) camera is a type of 35mm or medium format camera in which a system of mirrors and a pentaprism allows the photographer to see exactly what the lens sees. This reflex mechanism ensures precise composition, framing, and focus, as the viewfinder image corresponds directly to the captured photograph.
SLR cameras are valued for their versatility, interchangeable lenses, and accurate viewing, making them a popular choice for both professional and enthusiast photographers across a wide range of genres, from portrait and landscape to sports and wildlife photography.
