P, S, A and M modes
A (Aperture-Priority Auto) Mode
Set the aperture value and shoot pictures (A 48).
1 Rotate the mode dial to A.
2 Rotate the command dial to choose
the f/-number (aperture value).
When the camera is zoomed all the way out,
aperture can be set to values between f/2.8
and f/8.0; at maximum zoom, aperture can
be set to values between f/4.5 and f/8.0.
3 Focus and shoot.
At default setting, the camera automatically selects the
focus area containing the closest subject, from nine focus
areas, and adjusts focus accordingly (A 102).
B A (Aperture-Priority Auto) Mode
If the selected aperture would result in the picture being over- or underexposed, the aperture
display will flash when the shutter-release button is pressed halfway. Choose another aperture and
try again.
B Note on Shutter Speed
When Continuous, BSS or Multi-shot 16 is selected for Continuous (A 98), or when a setting
other than Off is selected for Auto bracketing (A 101), the slowest shutter speed available is
down to 1/2 sec.
D Aperture and Zoom
Aperture is expressed as an f-number, which is the ratio of the focal length of the lens to the
effective diameter of the opening (aperture) through which light enters the camera. Large apertures
(expressed by small f-numbers) let more light into the camera, small apertures (large f-numbers) less.
When the camera is zoomed out, the focal length of the lens diminishes and the f-number
decreases. When the camera is zoomed in, the focal length and f-number increase.
The COOLPIX P80 has a lens with a focal length of 4.7–84.2 mm and an aperture of f/2.8 to f/4.5.
