In reviewing some pictures taken recently with my D2H, I have found that I am having a weird problem during long exposures at night. It only seems to happen in exposures longer than ten seconds, and only when there are bright light sources in the frame somewhere. The problem shows itself as magenta colored 'fogging' in the lower corners of the picture, or in the right-most corners of a vertically oriented picture. I have seen the result with 3 different lenses (12-24dx, 28/2 ais and 50/1.8 ais), all with similar results. It looked like some sort of flare, so I didn't notice it at first, but I have seen it in several different shooting sessions, all under similar conditions as described above. I am not 100% certain, but I believe it has happened both with and without the long exposure noise reduction turned on.
Anybody have any issues along these lines with their D2H or other D series Nikon Body?
