A mirrorless camera, also referred to as a system compact camera, is a type of digital camera with interchangeable lenses. Unlike a digital single-lens reflex camera (DSLR), its body lacks a reflex mirror and an optical viewfinder. Light therefore passes directly through the lens to the image sensor. The image captured by the sensor is displayed in real time on the rear screen or in the electronic viewfinder, which is essentially a small display inside the viewfinder. This allows the photographer to see a precise preview of the future photograph, including all settings such as exposure or white balance, even before pressing the shutter button. The absence of a mirror mechanism allows for the construction of smaller and lighter camera bodies and lenses. Another feature is the ability to shoot silently using an electronic shutter, as there is no mechanical mirror movement.
