I'm confused. When in continuous shooting mode, either low or high speed, my 7100 will only take 3 shots, and no more, regardless of how long I hold down the shutter release. I have checked d6 - max continuous release and it is set to 100. I would expect the camera to keep taking photos even at a much slower rate as it writes to the card. I tested this with all qualities from raw down to small JPG basic, ISO 100, manual focus, manual shooting mode with no difference in the outcome, I can still only capture 3 shots and no more. (the display bottom right of the view finder says [r05] What am I doing wrong?
