Note on Shutter Speed
When

other than
Off is selected for Auto bracketing (A 101), the slowest shutter speed available is
down to 1/2 sec.

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.
