On Nikon issues service advisory on D600's dust issue article (240 comments in total)

I think we need to know which camera's serial number that has the problem, or if the problem happens to all D600, including the ones that people are going to buy tomorrow.
I have not looked in too much details on my photos. It does not seem an issue for me, but mine is still under 2000 shots and I am not a pro. Perhaps my camera series no. is not affected?

OneGuy: Sensors are funny. The cells within pixels do not uniformly detect all frequencies of light. Some "neon" colors really put a lot of energy into the pixels.

The "blooming" effect is a bit different. There is bleeding of energy into neighboring cells, which gets amplified by the on-chip circuits.

Because the fuji orbs are especially pronounced at reflections (although I saw pics of car headlights orbing and almost doubling the headlights), it appears the fuji sensor circuits are especially sensitive to polarized light. So, although technically one can use a polarizer (not possible w/ X10) to cut down on particular geometric sensitivity, it also points to a fundamental sensor problem. Fuji plays a lot with sensor geometry (hey, they say, it's different and "better" than Bayer) but it seems their knowledge of physics is wanting.

It is likely that internally fuji thinks it is a small problem, but I'd extend their incompetence to all of their sensors.

I found that the "orb" like object sometimes related to out-of focus issue (or some problem with the AF with the flag comes up). In this case, and in my camera, they appears more like a round bokeh.

I am just wondering if such a problem can be solved by making it into a star. Just like the old way to remove red eye problems... you just replace the red dot with a dark colour representing a non red eye pupil. I wonder if the same remedy can be applied, by replacing the "orb" with a star (of difference size). I even wonder if there is already third party softwarethat can do this.
The orbs did not bother me at all. I usualy can work around it. But again, I am not a professional.

Octane: 500x500 pixel? I see the potential, but I fail to see who would buy a camera with such a low resolution. Being able to change the focus is fun and cool as a demo, but the reduced resolution is too much of a compromise. It makes it virtually useless for any use.

Considering the digital camera eye can capture images while the focusing mechanism is working to achieve the sharp object, I think this technique can work. When the camera focus on a subject, it can capture within that microsecond of the same image... except it captures on the spectrum or depth of field of the subject. Did not Olympus produce a camera a few years ago that capture object with plus and minus miliseconds before the shutter button clicks? I think this concept can be converted to create images while the camera is focusing the object.
