5D3 dot of dust on focus area

[gjc10212]

OCD is creeping in, new 5D3 arrived yesterday all perfect no issues. However, after taking a few shots a tiny speck of dust or other material has appeared on the focus grid. Same as this: http://forums.dpreview.com/forums/read.asp?forum=1032&message=42388615

Will mirror up and rocket blower move it? Don't really want to ship it back to HK under warranty. I'm more inclined to pay fixation to clean it.....

I have a tiny spec on mine which I believe is also behind the focusing screen. Not sure whether it was there from new, as I only spotted it against a bright background. Immediately after that it really annoyed me as my eye was drawn to it every time I looked through the viewfinder. When I actually next used the camera to shoot, rather than just looking through, I forgot it was even there.

I believe the focus screen is located upwards near the prism, so not really something that is easy to clean yourself.

I don't really notice either, but the OCD is strong on this. Hopefully it will disslodge itself.
