Note that regardless of the option selected, there is no limit to the number of photos that can be taken in a single burst when a shutter speed of 4 s or slower is selected in exposure mode S or M.
The Memory Buffer
Regardless of the option selected for Custom Setting d2, shooting will slow when the memory buffer fills (tAA).
