About me:

Kodak DCS420c&m, Nikon D1, D1x, Sony DSC707, Kodak DCS Pro14n, Canon D300. I am currently modifying digital cameras and using them as aerial remote sensing tools, as well as developing/adapting methods for digital photogrammetry, multispectral classification and feature extraction. Taken 50,000+ digitals for natural resource/environmental monitoring & management, disaster prevention/evaluation, urban growth studies, project development (touristic & commercial) and laboratory scientific imaging.

Hi. I had similar issue with D800. I am still very happy with the things this camera does, but was very surprised to find dust and several round blobs (oil spots, I guess), after just 1 month of use. There were more spots on the sensor, than any other of my digital cameras have accumulated in years, even when they have been opened, modified, and abused. 18 spots, some easily visible over sky or other uniform subjects.

Since I had been shooting at 3 second intervals for up to one hour for several days, I initially thought that I was demanding too much from the D800, but my D2x was working in parallel under the same conditions and has only 3 small spots.

Carefully cleaned it myself with Sensor Swabs and methanol (it took three swabs). I have experience in assembling critical items in a clean room, lots of work to do and no time to send it in for cleaning. I hope someday it will stop shedding particles. I will keep on checking frequently, to see how it goes.

Carefully cleaned it myself with Sensor Swabs and methanol (it took three swabs). A few days later, made some aerial shots and checked for spots before take-off, but another large particle appeared. It could have spoiled an expensive job (travel, rent, airplane, etc.). I hope someday it will stop shedding particles.
