Remaining Exposures (Continuous Mode)
When the shutter-release button is pressed halfway in continu-
ous mode, the number of consecutive photographs that can be
taken before the buffer fills is displayed in the control panel on
top of the camera. This indicator shows forty when the buffer is
empty, and is reduced by one for each photograph in the buffer.
Note that depending on the amount of memory remaining on
the memory card, the maximum number of photographs that
can be taken in a single sequence may be less than forty. In
single-frame mode, this indicator shows the number of expo-
sures remaining.
