2-second release priority

When the exposure mode is set to
multiple pictures in rapid succession without having to wait for
the camera to measure focus and exposure for each picture.
Release and then re-press the
within 2 seconds after taking a picture, and the camera takes
the next picture using the same focus and exposure
measurements as the previous picture.

Noise Reduction for Long Exposures

At longer shutter speeds the camera will automatically take a
second exposure with the shutter closed in order to measure
and reduce the noise (grainy look) in the image. In these cases,
the exposure will seem to take twice as long as expected. For
example, in a 1-second exposure, the active display will stay
dark for 2 seconds until the noise reduction frame is exposed.
This means that at longer shutter speeds, you may not be able
to take quite as many shots back-to-back.
