Pixinfo.com have reviewed the dust removal systems of 4 recent DSLR cameras - the Canon EOS 400D, Sony A100, Olympus E-300 and Pentax K10D.

“Our goal was to set up a controlled environment to get the image sensors of digital cameras dirty and test how effective the different cameras’ sensor cleaning technologies are. It is well known fact (and it is a bit over dramatized) that digital SLR cameras are very sensitive to the dust particles found in the air. These particles can settle on the image sensor, and will show up on the images as dark spots when the image is taken with a small aperture (high F number).”
