I've had flawless use with my D300s until I began to notice what I initially felt was a seemingly random series of over and underexposed pictures with most of the images on both my CF and SD cards (I use JPEG and RAW with my CF as my overflow card and I used P mode for most of these pictures). Usually, when I review my images, I usually have the playback in single pic mode so I wasn't aware of any pattern. It was only when I zoomed out to the 72 pic mode that I noticed the patterns that are included below. (The top pic is my CF card and the one below is the SD card). There is a perfect vertical columnar delineation separating the over and under exposed pictures and the "degree" of abnormal exposure appears to occur in a repetitious gradient. Furthermore, the problem exists on both the CF and the SD cards. Although only 8 horizontal rows are depicted below, the dividing vertical column is usually pretty constant for 80 or 90 rows, but if I keep scrolling up or down on either card, the pattern might shift left or right, for example, so that maybe only the 2 or 3 farthest right columns are overexposed, or maybe the three on the left overexposed. At times, it even goes away. It's occurred on a number of different cards.

The problem has been intermittent and seemed to have cleared somewhat since as reset the camera, but because it's been an intermittent situation, I'm afraid to take my camera with me for some upcoming overseas travels. Maybe it's coincidental, but the problem has only occurred with outdoor daytime photos.

Has anybody heard or come across anything like this?
