Exposure warning signal: Should a “beep-beep” sound be emitted, note the position of the needle in the
shutter speed scale. If it swings past 1/1000sec. and stays within the red zone, overexposure will result. In
this case, reset lens aperture until the sound stops or the needle “drops” from the red zone; despite the
sound, correct exposure is possible. If the needle is around 1/30sec. or below, the sound merely warns
you that camera shake may affect image sharpness because of the slow shutter speed. You either read­
just aperture until the sound stops, or, if the needles is below 1/30sec., use a tripod to prevent picture
blur. The meter remains switched on for a brief period even after your finger is lifted off the shutter
release button.
Notes: 1. At approximately 1/1000sec. or 1/30sec., a shrill sound may be emitted; it becomes regular when the
needle goes beyond these points.
2. It is possible you won’t hear the warning sound in noisy shooting situations.

Tripod recommended to prevent Correctly exposed
camera shake (Below 1/30 sec.)
don’t take hand-held pictures at shutter speeds
slower than 1/50sec., and with a 135mm, try to use
a minimum speed of 1/135sec. Remember, this
presumes your subject is not moving. If it does,
you’ii need faster speeds—in which case you just
open the iens aperture.
Q. What shutter speed is best to use?
A. The shutter speed shouid be fast enough to pre­
vent camera shake, especialiy in hand-held shoot­
ing. In dim iight, you may not be able to get a high
speed. As a ruie of thumb, use a tripod if the shutter
speed is siower than a number equal to the focal
length of the lens. For example, with a 50mm lens,
