You rarely get a second chance in
photography. The ideal moment is
unrepeatable. Yet the tiniest spec of
dust entering the camera during a lens
change could ruin a perfect photo.
In analogue cameras, the dust parti-
cles are transported away as the film
is wound on. This means that usually
only one picture will be affected.
In contrast, dust landing on the image
sensor of a digital camera stays where
it is – and more will join it over time.
Even the smallest particle can cover
hundreds of pixels. This results in
image flaws that must be corrected
through subsequent editing. In addi-
tion, photographers must endure the
time and expense associated with re-
gular professional cleaning that conse-
quently becomes necessary – which
sometimes even requires the camera
to be sent away for servicing.
how the “Supersonic
Wave Filter” protects the
E-400 image sensor:
The dust filter, located in front of the
highly-sensitive CCD, is brought into
vibration via an ultrasonic generator.
This lets dust particles be shaken off
within milliseconds, which are then
captured on a special adhesive mem-
Dust particles have

The image sensor is put at risk through dust entering during lens changes.

from the dust filter.

The extremely compact body of the E-400,
with its fill of functions, was designed in strict
accordance with ergonomic considerations.
In practice, this means each button is located
exactly where it belongs and where one would
instinctively expect to find it.
Take it out of the box and start shooting
immediately – it can be that easy.

is invoked at each start-up of the

dust protection system is included in
all E-System cameras, and was again
optimised for incorporation in the
E-400 through a smaller form and
