Shake That Dust Off From Your Camera: Canon EOS Digital Rebel XTi

Every photographer knows that even the tiniest speck in the camera lens can prove disastrous in any photograph. With this issue in mind, Canon produced their own version of a dust-shaking camera. Canon EOS Digital Rebel XTi SLR camera uses a Self Cleaning Sensor Unit to shake that dust away from the camera. It uses ultrasonic vibrations to shake dust off of the surface that keeps the low pass filter in front of the camera’s sensor clean. These ultrasonic vibrations can be activated for one second each time the camera is turned on or off, or via a command in the menu.

The dust that shakes loose from the camera is then captured into an adhesive strip so it won't float back onto the filter. Of course this technology doesn't guarantee a 100% dust-free camera lens, but in case that a speck or two remains, users can activate the Dust Delete Data function. This maps the size and place of any remaining dust, and the mapping information is attached as metadata to subsequent photos. Users can apply the dust delete function after they transfer the photos to a computer which subtracts the dust image from the photo.

The 10.1 megapixel EOS Digital Rebel XTi will be available in mid-September for the price of $899, which already includes a zoom lens kit. This model is Canon's latest offering right after releasing the EOS Kiss.
