About RAW

Maximum Burst During Continuous Shooting
The maximum burst during continuous shooting indicated
on the preceding page is the number of continuous shots
that can be taken without stopping, based on a formatted
card.
In the viewfinder, the approximate maximum burst is
indicated on the right side.
<1
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 [.O.C.Fn II -2: High ISO speed noise reduction] is set to [2: Strong],
the maximum burst will be greatly reduced (p.214).
B 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 on the top LCD panel and in the viewfinder and shooting will
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 61.
The maximum burst indicator in the viewfinder will not change even
when you use a UDMA CF card. However, the maximum burst shown in
parentheses on page 61 will apply.
