Default Sensor dust...or lack thereof!!!

Considering how exposed m4/3 sensors are (no mirror in front of them providing some sort of protection) compared to all other DSLRs, I'm amazed by the fact that I never hear/read people say that they got dust on their m4/3 camera sensor. I have three m4/3 cameras right now (and had the EP1 for a while) and never ever had a single speck of dust on their sensors. I probably switch more lenses on my m4/3 cameras than on any previous DSLR I've had, primarily because of all the MF lenses that I shoot with. So, it made me wonder what the deal is. It's not just Oly having an efficient dust removal system because I have the Pana G1 and GH1 and they too are dust free. Very interesting indeed. Any guesses?

i think that goes for the majority of modern dslr and evil cameras. the dust reduction has improved alot recently.

i have had to use the rocket blower on my epl1 a couple of times, but considering how much i change the lenses and very rarely take any precautions to point it down or anything remotely intelligent like that, its not bad.

Um there's no mystery...Panasonic uses Olympus dust reduction system, SSWF, so there's nothing to wonder about...it just works. Of course if you get something sticky on the sensor like pollen you have to clean the sensor (SSWF filter) with a swab.

I've used my Oly E-300 now for 6 years now, and never had to manually cleaned.

Some people have owned the E-1 even longer and never had an issue.

Makes sense. I had a Pentax K100D and got sensor dust (despite the fact that I'm always very careful when I switch lenses). I read posts all over the place from people asking for help with this problem but I don't believe I came across any one with a m4/3 sensor dust issue.

The Pens are definitely the ultimate dust test with no mirror and shutter stopping anything from getting through on lens changes. I've done way more than my share of lens changing in shooting my E-PL1 with no hint of any foreign objects making their way onto the sensor.
