Quote - I don't see the need yet to perform any (manual) sensor cleaning. After two years of using the Olympus E-500 and changing lenses, there hasn't been one single speck of dust in sight. So it must be true what they're saying about Olympus' dust reduction system (the most efficient on the market today)...

Well, until you step into an E-3.  I have to clean mine about once a month.  I've seen a few reports from E-510 owners as well complaining of dust.  Some blame it on Live View, some blame it on in-body IS.  So it would appear that while still good, Oly's SSWF isn't as great as it used to be.

Like you, I've never seen dust on my E-500, and only once on one of my E-1s.

I use an arctic butterfly and a rocket blower on the E-3.  If I ever need a wet cleaning I'll send it in.
