Supersonic Wave Filter

CCD

In photography, it’s rare to get a second chance to take the shot. If the moment is missed, it’s gone. The most captivating picture can be ruined by the tiniest of dust particles that enter the camera body during lens changes. In analogue cameras, dust particles move with the film as it winds forward so that in most cases only one single picture is affected. In digital cameras, however, dust particles that settle on the image sensor stay there, accumu- late over time, and affect every picture. Merely microscopic particles can cover several hundred pixels on the CCD.

That not only spoils pictures but also

requires professional cleaning, which

costs time and money.

The effective solution for the E-500:

The Supersonic Wave Filter is located directly in front of the highly sensitive CCD. Powered by an ultrasonic generator, it produces vibrations that shake off the particles of dust. They then adhere to a specially-coated membrane inside the camera body and no longer pose a risk to image quality. This process takes mere milliseconds and is executed each time the camera is turned on or whenever Pixel Mapping is invoked.
