FWIW, I don't think that blowing with a high speed stream of air just blows it around inside the camera. The camera body is quite a shallow 'well'. I suspect, and practice seems to back up, that dust (at least the vast majority) is blasted out the front, since the air stream is reflected and directed back, that's the only place it has to go. Not trying to forcefully argue the point.

It just seems to me that there's so much excess angst regarding sensor cleaning and the infinite splitting of hairs over *the* method.

Manufacturers of cleaning systems and supplies have much to gain by making this a critical issue.

In my particular circumstances and usage I don't find sensor dust to be a major issue. I've never had anything actually stuck on the sensor. Just small pieces of dust laying on it. I clean the sensor, it takes less than 30 seconds, and I'm back shooting again.

I don't know, maybe it is not possible to get stuck dust from compressed air but I don't need to use it any more since pec pads work
fine and actually remove the dust, not just move it around in the camera.
