Got a couple thousand shots on my 1DmkIII now and so far, the sensor is still clean, checked it today. My 30D's was dirty out of the box and my 5D's was a mess, pretty much always. My 1DmkII was used with 4K shutter clicks on it and it was pretty bad too by the time it was in my hands.
Now... if anything I change lenses more often now than with any of those bodies.
I'm thinking this sensor cleaning gimmick might just work!
Anyways......just a observation
