The smaller and lighter the camera body, the greater the
hand-shake effect during shooting. LUMIX G/LEICA DG
lenses feature MEGA O.I.S., an image stabilizing function
that has been highly evaluated by compact camera users.
An internal LSI processes the output of the system's gyro
sensors approximately 4,000 times a second to provide
accurate compensation for even tiny amounts of hand-
shake. Unlike image stabilizing functions that are built into
the camera body, this highly accurate function also lets you
check the compensation effect directly through the Live View
Finder or on the LCD. The images that you capture have the
same shake-free beauty as what you see on the Live View
Finder or the LCD. The compensation effect is also carefully
matched to each lens. MEGA O.I.S. is especially effective for
hand-held shooting with a zoom lens.

These cutting-edge technologies support the compact size, light weight, and high-quality images of the LUMIX G Micro System.
The LUMIX G/LEICA DG lenses are manufactured by
an integrated production system in the Panasonic
Yamagata Plant in Japan. From lens processing to
assembly, inspection, and individual packaging, all
processes are conducted in Clean Rooms according
to rigorous environmental standards. For example, to
inspect aspherical lenses, we use an instrument called
the UA3P Ultra-Accurate 3D Profilometer, which was
originally developed by Panasonic and now plays an
essential role in the development and manufacturing
activities of many optical device manufacturers. Using
this instrument, with its measurement accuracy
of 1/10,000 mm, we conduct objective, numerical
evaluations. These criteria are then used to determine
the presence of flaring, the color of coatings, the
operating feel of the focus ring, etc., in order to ensure
high-quality production control. As a result, the quality
of Panasonic lenses has
gained high worldwide
acclaim for accuracy and
image quality.

In conventional digital SLR cameras, contrast AF is
more accurate than phase difference AF, but it has
a slower focus speed. LUMIX G/LEICA DG lenses
overcome this problem by incorporating a unique
stepping motor in the drive system. A screw unit
integrated with the motor shaft moves the focus lens
directly, without relay gears or cams. Auto focusing is
swift and accurate. Some lens models are equipped
with a linear motor to further reduce drive noise –
ideal when recording movies with sound. The number
of mount signal contacts has been increased from the
9 used in conventional Four Thirds System cameras to
more accurate than phase difference AF, but it has
a slower focus speed. LUMIX G/LEICA DG lenses

To assure superior image quality while reducing size
and weight, each LUMIX G/LEICA DG lens features a
number of aspherical lenses that effectively prevent lens
aberration, such as spherical and distortion aberration.
Each aspherical lens has the effect of several spherical
lenses, so a higher magnification ratio can be achieved
with fewer lenses. The result is smaller overall size and
weight. Aspherical lenses are extremely difficult to produce,
however, because they demand high dimensional accuracy.
In the past this restricted the applicable lens shapes and
materials, but Panasonic has made great strides in this
area. Our Yamagata Plant began developing cutting-edge
production technologies for molded lenses early on, and
today the plant manufactures a wide variety of lenses
– including concave lenses that have a large thickness
difference and measure a
mere 0.3 mm at the thinnest
part. The aspherical lenses
with superb image rendering
ability produced at this plant
now see widespread use.

Aspherical Lenses
In a conventional lens made only of optical glass, it
becomes difficult to correct chromatic aberration when
the focal length is long or the angle of view is wide, thus
resulting in contrast degradation or color bleeding. This
problem has been solved by Panasonic's Extra-Low
Dispersion (ED) lens. It suppresses the prism's color
separation effect to correct
lo n g i t u d i n a l c h ro m a t i c
aberration at the telephoto
zoom setting and chromatic
difference of magnification
at the wide-angle setting.
The ED lens is used mainly in
LUMIX G/LEICA DG telephoto
lenses and wide-angle zoom
lenses to render sharp, high-
contrast images with clear
colors from corner to corner.

Utmost caution is exercised in coating the LUMIX G/LEICA
DG lenses to suppress ghosts and flaring, while ensuring
optimum color balance. In addition to a standard broadband
anti-reflection coating, LUMIX G/LEICA DG lenses feature a
coating that reduces the reflectance of light that enters at
an angle. This multicoating process is widely used on lenses
with a small radius of curvature, such as those in ultra-
wide-angle lenses and fisheye lenses. It greatly improves
the image rendering performance when shooting against a
light source. Moreover, the
bonded surfaces of cemented
lenses are also given an
original multicoating process
to further reduce reflection.
This results in high-quality
images with superb clarity.
