Button

Depressing the button halfway switches
on
the exposure meter
and autofocus function and activates the viewfinder
LED
and
LCD
displays for focus/exposure information. Both displays stay
on
for approx.
16
sec., even after taking your finger off the but-
ton, then turn themselves off automatically
to
conserve battery
power. Depressing the button
all
the way down releases the
shutter.
The
shutter release button
is
threaded
in
its center to
accept a standard cable release for tripping the shutter with the
camera mounted
on
a tripod.
Notes:
1)
The
shutter cannot be tripped using the shutter release button unless:
a) the camera's power switch @
is
turned
on,
b) the film advance lever

is
stroked completely to cock the shutter, and c) the batteries are
in
proper working order.
To
release the shutter when the batteries are
dead, use the backup mechanical release lever ®, referring to the
next page.
2)
At the B setting, unless you hold the shutter release button down all
the
way,
the shutter may close prematurely.

Release
Lever
(6
T
his
lever
is
provided
as
an
alternative method of releasing the
shutter
in
case the camera's batteries become weak or com-
pletely exhausted.
To
operate the lever, first use your fingernail
to
pull
it
down to the ready position.
Then
push it down
to
trip
the shutter.
The
shutter operates at a mechanical speed of
approx.
1160
sec. at any setting
on
the shutter speed dial, except
T.
At
T,
push down the backup mechanical release lever with
the power switch
@ off.
Caution: If you advance the film while holding down
the
backup mechan·
ical release lever, the shutter will fire immediately at the completion
of
the film advance stroke, thus wasting a frame. Also,
if
you fail to advance
the film completely and then use the lever to trip the shutter, the mirror
® will remain
in
the "up" position; when the additional stroke
is
made to
complete film winding, the shutter will fire, also wasting
a frame.
