[] Aperture and Zoom
Aperture is expressed as an _number, which is the ratio of the _cal length of the lens to the effective
diameter of the opening (aperture) through which Iig ht enters the camera. Large apertures (expressed
by small _numbers) let more light into the camera, and small apertures (large _numbers) let less light.
This camera has a lens with a focal length of 4.6 120 tom and an aperture of f/2.8 to f/5. When the
camera is zoomed out, the _number decreases. When the camera is zoomed in, the _number
70 increases.
