The nature of CCDs is such that noise in the recorded image
increases at slow shutter speeds. This camera, however,
applies special processing to images shot at shutter speeds
slower than 1.3 seconds to eliminate the noise, thereby
producing high-quality images. (However, a certain amount of
processing time may be required before the next image can be
shot.)
z
The shutter speed, zoom and aperture value have the
following relationship.
z
The fastest shutter speed for flash synchronization is 1/500
second*. Therefore, even if the shutter speed is preset to a
speed higher than 1/500 second, the camera automatically
resets the shutter speed to 1/500 second during shooting.
* When using an external flash, see pp. 266, 267.
Shutter Speed Display
z
The following shutter speeds can be set. 1/160 indicates
1/160 second. Also, 0"3 indicates 0.3 second and 2"
indicates 2 seconds.
z
You can change the combinations of shutter speeds and
aperture values without altering the exposure (p. 135).
Safety Shift
With and modes, if [Safety Shift] is turned [On] (p. 55) in the
menu, the shutter speed or aperture value is automatically
adjusted for the correct exposure when it cannot be otherwise
obtained. Safety Shift is disabled when the flash is enabled.
