Warning Lamp
speod when using a standard &Omm lens. For
indoor photography, with no special iiiumi*
nation, choose 1/30 of a second and 1/60 ol a
second in a brightly lit room.
For outdoor photography, select 1/125
second when cloudy and 1/250 second in
sunshine. To take pictures in particularly
bright sunshine such as at a beach in mid*
summer or in snow*covered mountains, use
shutter speeds ol 1/500 sec. or 1/1000 sec.
The above mentiorwd shutter speeds
apply when using a standard 50mm lens, but
it is r>ecessarY to choose faster shutter speeds
when using lenses of longer focal lengths
because they are more difficult to hold
steady. It is generally said that the shutter
speed figure should be greater than 1 divided
by the focal length of the lens in order to ob­
tain sharp images.
For example, when usir>g a 200mm tele*
photo lens, shutter speed should be faster
than 1/200 second, therefore the shutter
speed in this particular case should be set at
1/250 sec. Image Ыиг can also arise if the
camera is not properly held. See page 31»
2 Reading the Exposure
This camera incorporates a magnetic
release system usir>g an eleciromagr>etic switch
to effectively perform instantaneous light
metering. The shutter release button activates
light metering and exposure in succession and
practically simuhar^usly.
This IS a two-step shutter button. The
exposure can be confirmed by the meter
needle inside the viewfinder by pressirsg the
shutter button halfway.
When the meter rteedle inside the view­
finder stays within the proper range and the
underexposure warning LED lamp below the
aperture scale inside the viewfinder does not
blink, the exposure is correct. See page 39
about the ur>derexpo$ure warning lamp.
When the ur«derexposure warning lamp
msidt the viewfinder blinks, or when the
meter needle moves into the upper over­
exposure warning гопе in red, the exposure is
incorrect. When this is the case, turn the
