Reported my problem at the begin of this post. Little follow up. Yesterday I took the camera to the shop where it was bought. The specks were noted and of course one was of the opinion that it was nothing but some dust and that they could clean it up. After three trials my camera was no longer dust free, the number of specks had increased, now consisting of the original ones that of course never moved, and some happily moving about new ones (dust alert). One was of the opinion that the problem was solved and that it was just some dust. Unfortunately for them I could easily show them the original stains again. Unmoved, still sitting tight. I was sent away and told to come back today, the repair service is next. This is the problem here in Holland. I never get easy exchanges. Always this pattern of it is you the client that has done something stupid, or just sees it wrong, or, anyway. Then it starts. I had this with a lens too, discentering, (da17-70) and it took all in all three months to have it back, repaired, sort of. Not the topic. Anyway, I am looking really forward to this trip.
Here I go again. I wonder what will happen. The least I want is them to remove the dust they introduced.
