2.Align film speed in use with the film speed index.
Note: Lines between the numbers on the film speed scale represent inter- mediate settings. (See illustration)

3. Select and set aperture.
The aperture scale window shows usable apertures. (Depending on film speed in use, all usable apertures may not be shown in the aperture scale window; for usable apertures, see table on page 20.)
For example, with the film speed index at ISO 100, you can select any aperture from f/2 to 1/22. Selecting f/4 lets you take pictures of subjects 0.8 m to 6.2 m (approx. 2.6ft. to 30ft.) away.
