+Don't expect "like crazy" (burst mode) to run without hickups. Cam has to wait for free buffer to continue shooting. Same may be happen with low duration settings in combination with high date rates (RAW) and/or cards with low write rate.
 > Internal note: ML menu shows (bottom line) calculation for time lapse duration depending on number of pics and interval. No idea how to represent this.
