Micro Four Thirds – the extended digital Interchangeable lens camera system standard

The open standard that led to the mirror-less body

The LUMIX G Micro System adopts the Micro Four Thirds System standard, developed as an extended version of the Four Thirds System standard for digital camera systems. Using this standard, and developing a camera body that eliminates the mirror box and optical viewfinder unit, the lens mount outer diameter was reduced by about 6 mm

(compared with the conventional Four Thirds camera) and shorten the flange-back
distance* by about half. Four Thirds System			Image Sensor

LUMIX G lenses: Superior portability, superior rendering

These interchangeable lenses, designed exclusively for the Micro Four Thirds cameras,

brings out the full potential of the 4/3-type image sensor. For instance, some aspherical
lenses and ED lenses can
ensure the impressive image
rendering even in the smaller
size than the Four Thirds lens.

Panasonic's renowned MEGA O.I.S.

The LUMIX G lenses incorporate Panasonic's MEGA O.I.S., the advanced optical image stabilization system that has highly proven in

LUMIX digital cameras. In the LUMIX G lenses, efficient stabilization elaborated by a special integrated LSI that processes output from the gyrosensors, which operate 4,000 times per second. This enhanced system helps achieve an exceptional hand-shake compensation performance.
