3. Choose aperture.

Determine the shooting distance and follow the appropriate vertical line upward from the distance scale until it meets one of the aperture/distance index windows for MD mode on the distance range indicators. Then follow the distance range indicator hori· zontally and you can find the appropriate aperture. For example, with film speed index set at ISO 100, and if you want to shoot a subject 3m away, use f/2 .8.

You can also determine aperture using the S8·22's guide number (GN). For details, see page 32.
