METERING MODES

The metering mode specifies the metering pattern.

Turn the metering-mode dial to the appropriate position to select the mode.

14-segment honeycomb-pattern metering - the camera’s standard metering mode appropriate for most photographic situations. By combining information on the subject’s distance and position from the autofocus system, this mode is less influenced by spot lighting or backlighting.

Center weighted - measures light values over the entire image area with emphasis given the central region.

Spot - uses a circular area within the image to calculate the exposure. Spot metering allows precise exposure measurements of a particular object without being influenced by extremely bright or dark areas within the scene.

Spot metering area

If the luminance levels of the scene are outside the metering range, the both arrows at each end of the Ev scale blink. In dark conditions, use the camera flash. Under bright light, use a neutral density filter on the lens to control the light levels.

CAMERA SENSITIVITY - ISO

Seven settings can be selected for camera sensitivity: Auto, 100, 200, 400, 800, 1600, and 3200*. The numerical values are based on the film ISO equivalent: the higher the number, the more sensitive the film.

Press the ISO button (1) to open the setup screen.

The left/right keys of the controller and the control dials change the setting.

Press the central button of the controller or the shutter- release button to complete the operation.

The auto setting automatically adjusts the camera sensitivity to the light conditions between ISO 100 and 400. As the ISO value doubles, the camera sensitivity doubles; a change of one Ev. Like grain in silver-halide film that increases with speed, noise increases with sensitivity in digital imaging; an ISO setting of 100 has the least noise and 3200 has the most.

A change in ISO also affects the flash range. The flash range depends on the aperture used:
