I have owned it since the day after release, it has near, or possibly over, 100K count on the shutter (haven't checked in a while). I have never cleaned it.
I have blown air on it a couple times (dog hair or large dust) but i have never cleaned it with a swab.............
I don't do a lot of lens swapping in the field, my 300mm or 11-16mm are usually glued to it, my "new" 70-200 VR-I is glued to it right now
when i change lens i always point the camera down and mate the lens
i have checked it at F22 a couple of times thinking "it MUST need cleaned" and seen some small small stuff but nothing i could find in any real photos.
don't know maybe I'm just crazy? also been a little hesitant to mess with the sensor
