Exposure Meter Index
If the Exposure Needle Does Not Center on the
Index
If an exposure or a shutter speed is improperly
selected, the exposure needle will not center on
the index. Reset the shutter speed or F stop until
the needle is centered.
You may use an ND (neutral density) filter if the
subject is too bright, or an electronic flash or flash
bulb if the subject is too dark.

Light Measuring Range of the Exposure Meter
The measuring range is EV 1.5-EV17 (ASA 100,
with F1.2 55mm lens). The list above summarizes
the lowest measurable limits in dealing with ex-
treme low light conditions.
CAUTION: If the aperture ring or shutter speed
ring is turned below the limits in the list, with ex-
tremely low lighting or the selector lever OFF,
the needle sometimes moves, but the meter is not
functioning.
