97 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.) Shooting Using the Mode Dial z The shutter speed, zoom and aperture value have the following relationship. Aperture Value Shutter Speed (seconds) f/2.8 - 3.5 15 - 1/2000 Maximum Wide Angle f/4.0 - 5.0 15 - 1/2500 f/5.6 - 8.0 15 - 1/4000 f/4.5 - 5.6 Maximum Telephoto f/6.3 - 8.0 15 - 1/2000 15 - 1/2500 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. 15" 13" 10" 8" 6" 5" 4" 3"2 2"5 2" 1"6 1"3 1" 0"8 0"6 0"5 0"4 0"3 1/4 1/5 1/6 1/8 1/10 1/13 1/15 1/20 1/25 1/30 1/40 1/50 1/60 1/80 1/100 1/125 1/160 1/200 1/250 1/320 1/400 1/500 1/640 1/800 1/1000 1/1250 1/1600 1/2000 1/2500 1/3200 1/4000 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.
