Mirrorless Cameras

While a DSLR camera uses a mirror mechanism to either reflect light into an optical viewfinder, or pass it through directly to the camera sensor, a mirrorless camera completely lacks such mirror mechanism (hence the name), which means that the light passing through the lens always ends up on the imaging sensor. Since light is no longer reflected on an optical viewfinder (OVF), mirrorless cameras typically rely on electronic viewfinders (EVF) and LCDs that basically project what the imaging sensor sees. Because of lack of a mirror mechanism and an optical viewfinder, mirrorless cameras can be made simpler, lighter and less bulky when compared to DSLR cameras.
