A digital mirrorless camera is a digital camera that accepts different lenses but does not have a mirror and mirror box to switch the scenes inside the camera from the optical viewfinder to the imaging sensor and shutter. Instead, most viewfinder functions are electronic. This allows the camera body to be smaller, thinner and lighter. These are also known as mirrorless interchangeable-lens (MILC) cameras.
Lightweight and portable, mirrorless cameras are perfect for photographers who want to keep their cameras at their side for capturing everyday moments. They offer high image quality, and the benefit of high-quality interchangeable lenses for various photographic needs.
