Olympus OM-PC, Instruction Manual

Page: 72 / 78

A: When using a 50mm F1.2, 50mm F1.4, 75 ~
150mm ZOOM or 35 ~ 105mm ZOOM lens,
the shutter speed displayed in the viewfinder
can differ from the actual one; but by approxi-
mately less than one stop. However, correct
exposure is always insured.
Q: Are there any lenses that cannot be used?
A: The 1000mm F11 lens cannot be used. The
following three lenses cannot be used in the
programmed mode. Use them in the aperture-
preferred auto mode or manual.
250mm F2, 350mm F2.8, 600mm F6.5
Q: My pictures tend to be overexposed when
shooting transparencies with flash in the pro-
grammed mode.
A: In this case, the pictures may turn out over-
exposed depending on the shooting conditions.
Use the aperture-preferred auto mode and stop
down the aperture.
Q: The shutter speed display and ESP mark
sometimes blink during metering.
A: In the case of a subject with an intermediate
luminance, the LED shutter speed display will
apparently blink because the adjacent figures
turn on alternately. When shooting under a
fluorescent lamp, they may blink more fre-
quently. The reason of this phenomenon is as
follows: Though the fluorescent lamp appears
to the human eye as if it were lighting con-
tinuously, it is in fact blinking repeatedly at a
frequency of 50 — 60 cycles a second. In both
cases, however, exposure is correct and there is
no problem at all.
Q: The flash does not fire.
A: The flash will not fire when the shutter speed is
faster then 1/60 sec.
Q: The shutter release button cannot be depressed.
A: You may not have wound the film properly,
or the film may have come to its end.
Q: Though the audible and visual signals do not
turn on when checking the batteries, the view-
finder display appears faintly.
A: If the battery voltage is extremely low, the
LED for viewfinder display may sometimes
turn on because the camera circuit allows it.
Q: Even when I gently push down the shutter
button, the viewfinder display doesn't come on.
A: Check the batteries by turning the Exposure
mode selector dial to the CHECK position. If
the batteries are all right, you have probably set
the camera to the "B" (Bulb) position on the
shutter speed dial. On "B" the finder display
does not light.
