The Mirrorless interchangeable-lens camera is a popular class of digital system cameras. Unlike a compact digital camera, a MILC is equipped with an interchangeable lens mount and unlike a digital single-lens reflex camera, a MILC does not have a mirror-based optical viewfinder. Various alternative names exist – see terminology – including: Compact System Camera, Mirrorless System Camera, Digital Single Lens Mirrorless, Digital Interchangeable-Lens System camera, and – finally – Electronic Viewfinder with Interchangeable Lens; this latter term not applying to cameras with an optical viewfinder. As of 2012 there were several MILC camera systems available. In chronological order and referring to the adopted lens-mount type, they are: Epson R-D1 using Leica M mount in 2004; Leica itself in 2006; Micro Four Thirds mount for Olympus and Panasonic MILCs; Samsung NX-mount for Samsung MILCs; Sony E-mount for Sony MILCs; Nikon 1-mount for Nikon MILCs; Pentax Q mount for Pentax small-sensor MILC; K-mount for both Pentax DSLRs and Pentax large-sensor MILC; X-mount for Fujifilm MILCs; and Canon EF-M mount for Canon MILCs.
