In developing the LUMIX G Micro System,
Panasonic set out to create a digital
SLR camera system with truly superior
mobility. This meant that both the camera
body and all lenses had to be extremely
compact and lightweight. The LUMIX G
Micro System's mirrorless configuration
achieves exactly that, cutting the flange
focal distance almost in half and reducing
the body mount radius by 6 mm. With the LUMIX G Micro
System, you get a camera that is light in your hands, easy
to maneuver, and a joy to use. And you get breathtaking
pictures thanks to an image sensor that's identical in
size to larger Four Thirds System standard cameras.

When a 35mm camera lens is used on a digital SLR
camera, sharpness and light intensity can be lost
and colors can bleed at the frame edges, where light
enters at an angle. Wide-angle lenses are especially
problematic since oblique light inclined at a large angle
tends to enter the peripheral areas. Not with LUMIX
G lenses. Created exclusively for digital use, LUMIX G
lenses are designed so that light can enter only from
straight ahead. You get superb rendering, with images
that are bright, sharp and vivid all the way to the corners.

The LUMIX G Micro System uses
a contrast auto focus (AF) system,
which maximizes the use of Full-
time Live View. Panasonic expanded
t h e n u m b e r o f m o u n t s i g n a l
contacts from 9 (the number used
in the Four Thirds System standard) to 11, to improve
data transmission efficiency between lens and body. This
helps achieve a contrast AF with levels of precision and
speed never before seen in a digital SLR camera.

The LUMIX G Micro System
not only shoots stunning
HD movies, it also features
the industry's first auto
focus lens that works when
shooting movies. And to
help you make even better
m ov i e s , Pa n a s o n i c h a s
introduced "silent design" lenses. These lenses use a
linear motor, so no drive sounds from the auto focus
system are recorded as you shoot. With the LUMIX G
Micro System, Panasonic opens the door to new kinds
of image expression. Explore the art of photography and
capture still shots of exquisite beauty. Or enjoy the fun of
shooting your own HD movies with a mobile, easy-to-use
digital SLR camera.
