APERTURE SETTING 125X B ow_ Preselection of the lens aperture is optional when shooting in the "M" (Manual) mode. However, when shooting on "AUTO", it is recommended that you preset the aperture. This is because the shutter speed selected by the automatic exposure system is determined in relation to the lens aperture used. By presetting the aperture control ring to an f-number that is appropriate for lighting conditions in the picture, problems of over and underexposure can be largely eliminated. When shooting on "AUTO" (or manual when applicable), preset the lens aperture as suggested in the following table. Fine weather Cloud weather Indoors f/8 - f/11 f/4 - f/5.6 f/1.4 - f/2.8 12 3 n 444 • 22151 85s 42e 215 `4\ To set aperture: The calibrations on the aperture control ring of the lens are referred to as f-numbers or f-stops and denote the size of the lens aperture. To set the aperture, align the figure equivalent to the recommended f-number with the diamond index mark. Note on f-numbers: Lower f/numbers (such as f/1.4) denote wider lens apertures, while higher-f-numbers (such as f/22) denote smaller apertures. With the 50mm f/1.4 lens, for example, f/1.4 is the widest, aperture or "open-aperture," while f/22 is the smallest aperture or "minimum aperture." As the size of the aperture also affects the overall sharpness of the photo, you may occasionally wish to vary the aperture setting from the norm for different effects (See page 32.) • 13
