High quality Panasonic optics Compatible with selected Micro Four Thirds system products Launched by Panasonic in 2008, the Digital Single Lens Mirrorless camera (more commonly \'CSC\') has revolutionised the world of creative photography. Mirrorless cameras combine compact ease of use with outstanding technical and control. The biggest difference between mirrorless and professional DSLR cameras is that they do not use a mirrorbox or pentaprism, as a consequence do not use an optical viewfinder. This enables DSLM cameras to have smaller camera bodies and more compact lenses. Instead of an optical viewfinder, a high resolution electronic viewfinder can be used which takes a live feed directly from the CSC camera sensor itself.
