Compact System Camera (CSC)
These are cameras with no mirror mechanism, and are therefore smaller and lighter than DSLRS (such as the Canon EOS M100). Mirrorless cameras still offer similar controls, high-quality images and interchangeable lenses. Depending on the model, there’s either an electronic viewfinder or no viewfinder and only the LCD screen. CSCS are also referred to as MILCS (mirrorless interchangeable lens camera) or EVILS (electronic viewfinder, interchangeable lens).
