Dust Removal Question

Verglace · 03-13-2011, 12:03 PM

I switched lenses yesterday from my 18-55 kit to a tamron 70-300mm. Started shooting random things all was fine. I then switched to live view and saw this peice of black crescent on the live view. I took photos and it was there, I then switched back to the older photos taken earlier and confirmed it was not there. I then used the dust removal function and after 1 try I saw that it had moved. So I spammed the dust removal function a few times and then it was gone. My question now is... where did it go, does it stay inside the body? If so is there any chance that if I were to hold the camera upside down or in portrait mode that it will go back to the sensor?

There's a lining of adhesive underneath the sensor- that dust isn't going anywhere

Oh okay that's good. I don't think it was dust though I think it was a price of plastic from the tamron back cover that was chipped off. But its gone now no need to worry I guess.

I'd worry more about a piece of plastic than dust. I'm not sure the adhesive on the newer cameras is designed to hold chunks of plastic.

What do you recommend I should do about it? I've used the camera a fair bit since and have used it upside down a few times and it has not come back, hopefully that's the last I'll see of it for at least a year (by then I should be ready for an upgrade)
