I only have one lens on the body, a Sigma 18-125mm. It does not seem to produce any dust on my D200 though, so the lens might not be the issue.
I make a point to NOT swap lenses in the field, or at all for that matter.
The vacuum does seem like a good idea, since there might be some dust trapped in the body.
