Shutter Speed and Aperture Readouts | Canon EOS-3 specification

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.

CF Custom Function CF-6 enables the shutter speed and aperture to be set in full-stop or half-stop increments. See page 112.
