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, aperture can be set to values between f/5.3 and f/7.3. 1 2 1/125 F4.3 9 Rotate mode dial to A. 1/125 F6.8 9 Choose aperture. 3 Take pictures. Camera automatically compares distances to subjects in nine focus areas and sets focus and exposure for clos- est subject (B 76). 1/125 F6.8 9 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. 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 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 (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.
