Dear All,

I was wondering if somebody else has the following problem or maybe knows how to deal with it.

Lately my Nikon D700 starts to overexposure alot in some shots. It looks like the sensitivity of the sensor goes up sometimes. I have included a sample serie of one bracketing serie of 9 shots. The mode was set to manual and the bracketing order is normal-under-over. The camera was placed on a tripod and all the shots were taken directly after each other. (the metering was set to matrix).

1st shot: DSC_6577.jpg (normal exposure, 1/8sec. f8 iso800) and indeed the exposure seems normal

2nd shot: DSC_6578.jpg (-4 exposure, 1/125sec. f8 iso800) this one seems right as well. Really dark but I think normal with -4 exposure.

3rd shot: DSC_6579.jpg (-3 exposure, 1/60sec. f8 iso800) this one is wrong in my opinion because it is almost as light as the photo with normal exposure and it should be -3.

4th shot: DSC_6580.jpg (-2 exposure, 1/30sec. f8 iso800) this one is darker as the -3 exposure one so it could be right because its also darker as the normal exposure.

5th shot: DSC_6581.jpg (-1 exposure, 1/15sec. f8 iso800) this one has the same exposure as the -2 exposure so one of them is wrong, both are darker then the normal exposure so one of them could be right.

6th shot: DSC_6582.jpg (+1 exposure, 1/4sec. f8 iso800) this photo is way more exposed then +1 so this one is wrong again.

7th shot: DSC_6583.jpg (+2 exposure, 1/2sec. f8 iso800) this one is darker then the +1 exposure but a bit lighter then the normal one so this shot could be right.

8th shot: DSC_6584.jpg (+3 exposure, 1 sec. f8 iso800) same exposure as the one with +2 so one of both is wrong.

9th shot: DSC_6585.jpg (+4 exposure, 2 sec. f8 iso800) really bright, not sure if +4 should be this bright.

The problem occurs using all kinds of different functions (so not only bracketing or something) but until now i did not discover a real order of when it happens.
One final remark. It looks like the problem only occurs while using the 24-70 2.8 lens..I did not have the problem using my 70-200 2.8.
Thanks for all your help!,

take care,

Dominic
