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, and small apertures (large f-numbers) let less light.
This camera has a lens with a focal length of 4.6-120 mm and an aperture of f/2.8 to f/5. When the
camera is zoomed out, the f-number decreases. When the camera is zoomed in, the f-number
increases.
