Numbers from 4000 to 4denote the denominator of the shutter speed fraction: for example, 125 is 1/125 seconds. Inaddition, 0"3 is 0.3 seconds, and 15" is 15 seconds.Aperture value readoutThe aperture value is normally displayed in 1/2-stop increments. The larger the number, thesmaller the aperture opening. The range of aperture values (f-numbers) displayed depends onthe lens used.The shutter speed and aperture value can be set in 1/3-stop increments.(C.Fn-4124)
