Anleitung Zusammenfassung
Setting the Aperture Shooting Mode The aperture adjusts the amount of light entering through the lens. When you set the aperture value, the camera automatically selects a shutter speed to match the brightness. Selecting a lower aperture value (opening the aperture) allows you to blur the background and create a beautiful portrait. A higher aperture value (closing it) brings the entire range from foreground to background into focus. The larger the aperture value, the greater the range of the image brought into clear focus. • If the shutter speed is shown in red, the image is underexposed (insufficient light) or overexposed (too much light). Adjust the aperture value using the or button until the shutter speed display turns to white. • Some aperture values may not be available with certain zoom positions (p.44). • In this mode, the shutter speed range with synchronized flash is 1/60 second to 1/500 second. The aperture value setting may therefore be changed automatically to match the synchronized flash speed even if its value was set previously. Aperture Value Display • The larger the aperture value, the smaller the lens aperture. F2.8 F3.2 F3.5 F4.0 F4.1 F4.5 F5.0 F5.6 F6.3 F7.1 F8.0* * In mode, the settings for maximum wide angle aperture and maximum telephoto aperture may be as high as F11 and F16, respectively, in some shooting conditions. • You can change the combinations of shutter speeds and aperture values without altering the exposure (p.53). Safety Shift With and modes, if [Safety Shift] is turned [On] in the Rec. 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. Shooting 45 Manually Setting the Shutter Speed and Aperture Shooting Mode You can manually set the shutter speed and aperture to shoot images. • When you press the shutter button halfway, the difference between the standard exposure* and the selected exposure appears on the LCD monitor. If the difference is more than ±2 stops, “–2” or “+2” appears in red. * Standard exposure levels are calculated by measuring light according to the currently selected metering mode. • If you wish to change the exposure, select shutter speed or aperture using the button, then adjust the value using the or button. • If the zoom is adjusted after these values are set, the aperture value may change in accordance with the zoom position (p.44). • The LCD monitor’s brightness matches the selected shutter speed and aperture value. When you select a fast shutter speed or shoot a subject in a dark place, the image will always be bright if the flash is set to (Flash on, with red-eye reduction) or (Flash on). Selecting an AF Frame * Shooting Mode * Cannot be set in and modes. The AF frame indicates the area of the composition on which the camera focuses. You can set the AF frame in the following ways.
