DSLR dust removal/ sensor cleaning shootout
"...The anti-dust capabilities (or lack thereof) of Canon's EOS-400D, Olympus' E-300, Pentax's K10D, and Sony's Alpha A100 were put to the test.... Essentially, each camera was given a before / after test shot in order to judge the results, and after the digicams sat through a dirtying process, they were "self-cleaned" 25 times and finally rated. Considering that Olympus was given credit as being the first manufacturer to include dust cleaning technology in its products....."
