I have been on a mission since seeing dust spots on my sensor, I drove to the camera shop an bought a 1.6 crop cleaning pack (4 swabs and the alcohol vial)
It didn't take one swab to do but took many tries and the sides of the swab were disgusting to say the least.(even after blowing the area out with a new blower)
After the first try I moved other close particles onto the sensor inadvertently
The results had me worried for a moment or two as it was more lubricant holding dust than a dust problem
It would be a safe guess to say it had never been cleaned before.
The final shot is my happy result after many efforts and using three of the 4 swabs and half the alcohol in the pack
I will get bulk supplies off ebay and do this on a 1000 shot basis or if needed before or after after looking for the dust spots.
A capture in f22 at full extension (max zoom with a zoom lens) with a long enough exposure time to swirl and move the camera around while aiming at a white well lit ceiling or clear sky will show em up as follows (new to me
and not being smug)
The fibres and residual dust suronding the sensor were the issue not the original dust spots (stuck to lube)
hence a new cleaning regime for the future ( what happens when the camera auto cleans the sensor , it vibrates off the sensor if your lucky ,,,,,into the closed area and sits and waits or circulates !!!)before

you can see the first swab ( swab 7 is the result and all previous were after blowing) and if you can see anything on the final let me know please but I reckon it is clean, now, finally !
(check out the lube smudge on 11 top left )
I can sleep now
I want to stand as close to the edge as I can without going over. Out on the edge you see all the kinds of things you can't see from the center.
