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). 1/125 F2.8 20 1/125 F3.2 20 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. 51
