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;
note, however, that frame rate will drop when the buffer is full.
While photographs are being recorded to the memory card, the access
lamp next to the memory card slot will light. Depending on shooting
conditions and memory card performance, recording may take from a
few seconds to a few minutes.
Do not remove the memory card or remove
or disconnect the power source until the access lamp has gone out.
If the
camera is switched off while data remain in the buffer, the power will
not turn off until all images in the buffer have been recorded. 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.
