i have checked the camera and it is not on bracketing. the shots are totally random, no progression. the first could be perfect or totally blown or totally underexposed. i can shot one image look at the histogram use the exposure button to increase or decrease exposure and the next image will be all over the board. the second and third, the same thing. this started with one aperture on one lens, the nikon 16-35 f.4. then it happened on a couple of different apertures on the lens and now it does it with all the lenses. all the lenses are nikon. manual mode no problems, auto exposure nothing but problems.
