Shutter Speed and Aperture Value Readouts
Shutter speed readout
The shutter speed is normally displayed in 1/2-stop increments. Numbers from 4000 to 4
denote the denominator of the shutter speed fraction: for example, 125 is 1/125 seconds. In
addition, 0"3 is 0.3 seconds, and 15" is 15 seconds.
Aperture value readout
The aperture value is normally displayed in 1/2-stop increments. The larger the number, the
smaller the aperture opening. The range of aperture values (f-numbers) displayed depends on
the lens used.
The shutter speed and aperture value can be set in 1/3-stop increments.
