Got a question. I don't have the D810 but some of its users from the site that I frequent seem to have come across a weird, never-seen-before type of noise... Can't post the pictures since I didn't ask for permission but I figured I can throw a question here... (I've posted the same question on the DPreview as well)
Basically, under certain environment and setting, a PCB pattern noise appears in the background. Here's the usual setting...
1. Body : D810
2. Lens : Sigma 35mm f/1.4 ART, Nikkor 24N, Nikkor 35N (the ones that's I've seen the issue from)
3. Environment : Night, landscape with buildings and sky composing 50:50, light source from the buildings
4. Shutter : 16
5. Exposure : 4 Sec or longer
6. ISO : 64
7. HDR : On
So far, about 4 or 5 people have found the PCB pattern in the background when the photo was taken with the above setting... Interestingly, the PCB patterns are all different. By the way, the pattern is usually not seen unless the curve is edited to bring up the level...
Anyone seen or can reproduce this noise with D810 or other bodies and lens???
