Now I have my new, used Nikon D700. And what I discovered: two dots in the picture!
The "shaking" the camera does not get the sensor clean.
Crap, again the stupid cleaning procedure. Or the camera to the service provide?
The seller of the camera had given me the advice to get me a pair of bellows with air filter.
So I have been looking at an Amazon.
Unfortunately, the vast majority of product descriptions are here not clear which of the bellows have a filter and which are not.
Then I discovered this here .... what a giant filter and ... what a price!
Yes, this bellows is very expensive.
I got the part anyway and ordered immediately after receipt at first tried a lens. The air of this bellows is actually clean.
For the liberation of the sensor (or the filter in front of the sensor) I then put a loupe, the crumbs searched on the filter (works best if you're looking in the bright reflection of the lamp) and the dirt blown off (with the bellows tip yes not touching).
Then again held the camera body upside down, all the corners of the mirror box fixed blown and the Camera tried: Clean!
From this experience, I would recommend this product.Are.
Only the manufacturer should pack the bellows with the top down, then you can keep the tip clean better, because you will not have to touch to unpack, I think.
Addendum: very clean, I did not get the sensor with this bellows but, as the check one's under a microscope (10x) shows.
Some crumbs appear to be simply sticky enough that they can not be blown away.
Fortunately, they are so small that they do not spoil the photos.
