Close
If the maximum burst is lower than the normal number, and the camera stops continuous shooting in mid-course, check the [High ISO speed noise reduction] custom function setting.
If [High ISO speed noise reduction] is set to [On] or [Strong], the number of continuous shots (maximum burst) will be lower. To reset the maximum burst to normal, select either [Standard], [Low], or [Disable] for [High ISO speed noise reduction].
Caution
When the [High ISO speed noise reduction] setting is enabled, more time is required to process noise reduction. As a result, it will take longer to temporarily save data in the storage space, and the camera is more likely to be interrupted during continuous shooting.
For information about the effect of using [High ISO speed noise reduction] on the maximum burst for the model you are using, please check the table below.
Also, for details on how to change the custom settings, please see the instruction manual supplied with the camera.

*1: With setting [2:Strong], the maximum burst for continuous shooting will greatly decrease. If either [0:Standard], [1:Low], or [3:Disable] is selected, the maximum burst will rarely decrease.
*2: Whether set to [0: Standard], [1: Low], [2: High], or [3: Disable], there is no effect on the maximum burst.
*3: With [High] or [Multi Shot Noise Reduction], the maximum burst for continuous shooting will greatly decrease. If either [Disable], [Low], or [Standard] is selected, the maximum burst will rarely decrease.
*4: When [Multi Shot Noise Reduction] is set, four shots will be taken continuously, then shooting will stop.
*5: When [Multi Shot Noise Reduction] is set, four shots will be taken continuously, then shooting will stop. If the image-recording quality is set to RAW or RAW+JPEG, you cannot set [Multi Shot Noise Reduction].
