Mirrorless cameras have gained a respectful base of followers in less than 4 years since first introduction. Panasonic and Olympus were first to break the ice and remove the mirror from interchangeable lens cameras. It proved to be a successful idea, quickly gaining market shares and other manufacturers soon followed with their own systems. One of the main early criticisms was toward the lack of native lenses, but those day are long past. Today, 38 lenses are available for use on Panasonic and Olympus micro 4/3 bodies. If you are tired of heavy DLSR cameras or lenses and ready to jump into mirrorless world, micro 4/3 system is your best gamble.

But if you care for image quality and wish to control the way final photo will look like, RAW is essential.
