Check the number of exposures
remaining.
The information display and viewfinder show
the number of photographs that can be stored
on the memory card. Check the number of
exposures remaining.
If there is not enough memory to store
additional photographs at current settings, a
warning will be displayed. No further pictures
can be taken until the memory card has been
s
replaced (0 20) or photographs have been
deleted (0 33, 101).
When enough memory remains on the memory
card to record a thousand or more pictures at
current settings, the number of exposures
remaining will be shown in thousands, rounded
down to the nearest hundred (e.g., if there is
room for 1,260 exposures, the exposure count
display will show 1.2 K).
