A The Memory Buffer
The camera is equipped with a memory buffer for temporary storage,
allowing shooting to continue while photographs are being saved to
the memory card. Up to 100 photographs can be taken in succession.
Depending on the battery level and the number of images in the
buffer, recording may take from a few seconds to a few minutes. If the
battery is exhausted while images remain in the buffer, the shutter
release will be disabled and the images transferred to the memory
card.
A
Frame Rate
For information on the number of photographs that can be taken in
continuous release mode, see page 344. Frame rates may drop when
the memory buffer is full or the battery is low.
A The Built-in Flash
Continuous release mode can not be used with the built-in flash; rotate
the mode dial to
j (0 25) or turn the flash off (0 89).
A Buffer Size
The approximate number of images that
can be stored in the memory buffer at
current settings is shown in the viewfinder exposure-count display
while the shutter-release button is pressed.
