Shooting in P, S, A, and M Modes

Shooting in A (Aperture-Priority Auto)

1 Rotate the mode dial to A.
F	1/125	F4.3	17

2Rotate 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/2.7 and f/7.6; at maximum zoom, aperture can be set to values between f/5.3 and f/7.3.

P, S, A and M modes

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 (A105).

BA (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.

BNote on Shutter Speed

When [Continuous], [BSS], [Continuous flash] or [Multi-shot 16] is selected for [Continuous] (A101), or when a setting other than [Off] is selected for [Auto bracketing] (A104), the slowest shutter speed available is down to 1/2 sec.

DAperture 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. In modes A and M, this effect can be minimized by selecting [On] for [Fixed aperture] (A109). Aperture can be controlled in the range of f/5.1 to f/7.3.

The COOLPIX P5100 has a lens with a focal length of 7.5–26.3 mm and an aperture of f/2.7 to f/5.3.
