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.

Overexposed (Above 1/1000 sec.)

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,
