The effects of [High ISO Speed Noise Reduction] on the number of possible shots for the maximum burst during continuous shooting (EOS 5D Mark II)
Solution
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] for custom function setting.
If [High ISO speed noise reduction] is set to [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].
IMPORTANT
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.
1. To change the [High ISO speed noise reduction] setting, display the menu screen and choose [C.Fn II: Image] on the [ 
] tab, then press <

] tab, then press < >.
2. Select the [High ISO speed noise reduct'n (Custom Function No.2)]. The [High ISO speed noise reduct'n] screen will appear, select either [0: Standard], [1: Low], or [3: Disable] for [High ISO speed noise reduction].
For more information, please refer to the camera's instruction manual.
NOTE
With [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.
