• Using a Remote Commander (either the one supplied, or another of your
choice) reduces the camera shake and continues the exposure without
pressing and holding the shutter button.
Notes
• When using a tripod, turn off the SteadyShot function.
• The longer the exposure time, the more outstanding the noise on the image.
• After shooting, noise reduction (Long exp.NR) will be done for the same amount of
time that the shutter was open. You cannot do any further shooting during the
reduction.
