Metering Sensitivity Areas
With the New Canon F-1, a special optical element in each focusing screen de-
termines the metering sensitivity area. Thus the metering area can be changed,
according to the sub ect you are shooting and the lens in use, simply by replacing
the focusing screen.
There are three different light measuring areau available, each designed to suit par-
ticular metering requirements.
1. Center-weighted Average Metering
With this system, the meter reads the entire viewing area with special emphasis on
the central portion where the subject is most likely to be. It can be used for general
photography, and is recommended especially for AE photography.
2. Selective-area Metering
The selective-area system, with its 12% coverage, allows you to meter a certain
portion of a scene. It, too, is suited for all-around use, and is particularly effective
for metering highcontrast scenes, such as landscapes with a bright sky and backlit
subjects. Manual exposure is recommended for optimum results. This system can
be used for AE photography, but special attention must be paid to ensure that the
subject is within the 12% metering area.
