It is almost impossible to prevent dust from getting inside
a camera body while lenses are being changed.
Yet just one particle of dust on a sensitive sensor
surface can lead to serious adverse effects for image
quality. Olympus’ Supersonic Wave Filter (SSWF) was
the world’s first dust protection system. Thanks to continual
improvements, it is still the most effective. Positioned
in front of the sensor, the Supersonic Wave Filter removes
dust at lightning speeds with the help of supersonic vibrations
at more than 30,000Hz. This powerful technology
functions at a molecular level where shaking motions and
static charges are no longer effective.

To ensure not a single image is damaged by dust particles,
the system automatically activates every time the camera or
its Live View function is switched on.
Solid magnesium body with all-round protection
against dust and moisture.
In order to be ready for any challenge at any time and
under any conditions, the E-3’s body is constructed to be
extremely robust as well as dust and water resistant. All
important components including the built-in flash and LCD
screen are sealed against the effects of sand, dust, rain and
water drops. Made of a “thixomold” magnesium alloy, the
body is exceptionally durable, solid and lightweight.
A wide selection of ZUIKO DIGITAL Pro and Top Pro lenses
also includes models that are protected against water and
dust. As with the E-3 itself, these lenses are sealed to protect
the camera at all times.
