We already know that megapixels don't matter (right?), but an oft
hyped (but untested) feature that has emerged on DSLRs is automatic
sensor cleaning. 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, and although the methodology was less than
scientific, the results were intriguing nonetheless. 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, it's not too surprising
that it took home the gold, but even sitting in first place, the
E-300's effectiveness was only rated at 50-percent. Canon's EOS-400D
came in with high expectations, but received a "poor" rating as the
cleaning effectiveness clocked in a paltry five-percent. If you
thought these two were bad, it only got worse when the Pentax K10D
and Alpha A100 stepped to the plate, as both highly-regarded cams
were deemed "useless" in the anti-dust department. So if your number
one priority in a new DSLR is how well it cleans up after itself,
there doesn't seem to be a standout option just yet, but feel free to
hit the read link and decide for yourself.
