Canon EOS 450D Digital slr camera Integrated Cleaning System

The Canon EOS 450D has a EOS integrated cleaning system this is implemented every time you start up your camera to remove dust.

A self-cleaning sensor unit creates a short burst of hi frequency vibrations to shake dust particles off the infared filter, this lasts for one second but is disabled when taking pictures after start up.

There are two other ways the EOS 450D reduces dust collection and the makers Canon have managed to reduce the dust generation with redesigned body cap that prevents dust collection through wear of the cap itself.

The last way is to repel dust from the low pass filter covering the front of the cmos sensor this is done by anti static technology to repel dust particles.
The last product to repel dust Canon have developed a internal dust delete system this maps out were visible dust that landed on the sensor and developed a software called digital photo professional software candelete from the image the dust particles when processed by the software.
