Shutter Speed And Aperture Readouts - Canon EOS-3 Instructions Manual

4. Shutter Speed and Aperture Readouts

● Shutter speed readout
The shutter speed is normally displayed in 1/3-stop increments. Numbers from "4" to
"8000" denote the denominator of the shutter speed fraction. For example, "125" is 1/125
sec. Also, 0"3 is 0.3 sec., and 15" is 15 sec.
● Aperture readout
The aperture is normally displayed in 1/3-stop increments. The larger the number, the
smaller the aperture opening. The range of aperture numbers (f-numbers) displayed
depends on the lens used.
Custom Function CF-6 enables the shutter speed and aperture to be set in full-stop
CF
or half-stop increments. See page 112.
