Hi everyone,

Does any D2X (or Xs) users has ever encountered banding with thess cameras?

Lately, my D2X has become more noisy from ISO200 up. First, I thought that my NR setting was off. I verified and it is as I set when I first had the camera 18 months ago.

Also, I got more surexposed pictures at ISO800 and higher than before.

Yesterday, I took 2 pictures at ISO800 and at home, I was surprised to find slight horizontal long banding across the whole image. I will conduct more extensive tests today.

I wonder if somehow, the sensor and its circuitry «drifts» with time and become noisier.

Any experience or input to share?

Thank you.

D2 banding - Update

Here's few pictures showing slight long banding. The banding is more evident in dark areas and worsen with high ISOs.

This picture was taken at ISO640. The exposure was boosted in NX by +1.5EV to make banding easier to see (although I can see banding in the original in the same areas).

Blowup of the left circle. You can see horizontal thick dark strips separated by light thin strips near the edge of the flower.

Blowup of the upper right circle. Banding can be seen within the circle, especially at its bottom.

Does anyone ever encounter this phenomenon?.
Any idea what may be the cause?

Thank you in advance for your help.
