Frame picture, focus, and shoot. • Press d to return to the Shooting mode. • If the selected aperture would result in the picture being underexposed or overexposed, the aperture icon on the monitor will flash when the shutter-release button is pressed halfway. Select another aperture and try again. Aperture and Zoom The aperture value (measured in f/-numbers) expresses the amount of light that passes through the lens and is calculated by dividing the lens' focal length by the effective diameter (a value based on the physical opening in the lens and the amount of light passing through). Lower f/-numbers indicate an increase in the amount of light passing though and higher f/-numbers indicate a decrease. The smallest number in a lens' aperture range is the maximum aperture and the largest number is the minimum aperture. The aperture for this camera's lens (focal length: 7.5 to 26.3 mm; aperture range: f/2.7 to f/5.3) changes depending on the zoom setting. The aperture increases when zooming in and decreases when zooming out. • Selecting On for Fixed aperture (P.88) in E (Aperture-priority auto) mode keeps the aperture change as close as possible to the selected f/-number (aperture range: f/5 to f/7.3). • In M (Programmed auto) mode, Fixed aperture has no effect even if set to On. 42
