P, S, A, and M Modes

A: Aperture-Priority Auto
In aperture-priority auto, you choose the aperture and the camera sets shutter
speed for optimum exposure. When the camera is zoomed all the way out,
aperture can be set to values between f/2.7 and f/7.6; at maximum zoom, aper-
ture can be set to values between f/5.3 and f/7.3.
If the selected aperture would result in the picture being over- or under-
exposed, the aperture display will flash when the shutter-release button is
pressed halfway. Choose another aperture and try again.
C
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 aper-
tures (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. In modes A and M, this effect can be minimized by selecting On for
Fixed aperture (
B 78).
The COOLPIX P5000 has a lens with a focal length of 7.5–26.3mm and an aperture of f/2.7
to f/5.3.
