Figure 12-6 The metering system. The metering cell is at the bottom of the camera and is
completely protected from extraneous light.
Figure 12-5 The metering area. The 205 (left) has a precise Spot meter that measures only
a small center area. In the 202 and 203 models (right), approximately 75% of the light is
measured within a 28 mm center area. The measured areas are indicated on the focusing
screens (bottom).
