I was out shooting with a friend yesterday...we both have D300s. We started out shooting multiple exposures in CL mode (we both have d4:CL Mode Shooting Speed set to 3). Both cameras shot as expected. Then we switched to CH mode. My friend's D300 shot again as expected...noticeably faster at around 6fps. My D300, on the other hand, shot at the same speed as CL...about 3 fps. I have gone over all of the menus and just can't find what I have set incorrectly. Does anyone have any thoughts?
