Maximum Burst During Continuous Shooting
The maximum burst during continuous shooting indicated on page 85 is
the number of continuous shots that can be taken without stopping,
based on a formatted 4GB card.
The number is displayed on the bottom
right in the viewfinder. If the maximum
burst is 99 or higher, "99" will be
displayed.
O
The maximum burst is displayed even when a card is not inserted in the
camera. Make sure that a card is loaded before taking a picture.
if [..,_.C,Fn I1-2: High ISO speed noise reduction] is set to [2: Strong],
the maximum burst will be greatly reduced (p.254).
If the viewfinder displays "99" for the maximum burst, it means the maximum
burst is 99 or higher. If the maximum burst decreases to 98 or lower and the
internal buffer memory becomes full. "buSY" will be displayed in the
viewfinder and on the LCD panel. Shooting will then be disabled temporarily.
If you stop the continuous shooting, the maximum burst will increase. After
all the captured images are written to the card, the maximum burst will be as
listed on page 85.
