On September 12, 2008, Panasonic announced the G1, a micro four thirds camera based on the 4/3 sensor in Olympus DSLR’s. This was the first of what we now call Mirrorless Interchangeable lens cameras. Or E.V.I.L (Electronic Viewfinder Interchangeable Lens) Or CSC (Compact System Cameras) As you can see things have moved fast from Panasonic and now we have Olympus, Sony, Fuji, Samsung, Nikon, Canon, Sigma, Kodak, Pentax, Ricoh and Leica offering products that fall under the Mirrorless umbrella.
