4) Shutter Release
Located on the front of the ALPA 10d
(D Fig. 2) the hair-trigger release instan-
taneouslγoperates the quiet
，
lightning-
fast reflex-mirror and smooth-gliding
，
vibration-free shutter. Press γour thumb
against the camera back in the opposite
direction
，
so as to hold your ALPA as
steadilγas possible. The conical thread
inside the release button accepts a
cable release. All lenses with automatic
diaphragm have integrated release but-
tons
，
which in turn depress the release
button on the camera. The flip-up
reflex-mirror immediatelγreturns to its
normal position
，
after the shutter is
closed
，
even ifγou keep the release
button depressed. Anγvibration γou
maγfeel is caused bγthe flipping
down of the mirror
，
which has no
longer anγinfluence on the sharpness
of the picture.
Important: Ifγou still depress the
release button when starting to wind the
camera
，
the mirror maγnot flip up for
your next exposure and one frame would
be lost.
The shutter release lock (V Fig. 2)
provides for light readings
，
previewing
depth-of-field and accidental exposure
prevention. The lock does not function
，
if
γou use a cable release in the release
button of the camera itself.
For extreme wide angle lenses with
protruding rear elements
，
the ALPA
mirror can be locked in its flip-up posi-
tion. Wind the high speed winding lever
，
holding it in its extreme position and
depress the camera release button.
Then release both release button and
lever. For smoothest possible shutter
release with extreme telephoto lenses
，
for ultra close-ups
，
photomicrographγ
，
etc. depress the release button very
slowlγ
，
so that the mirror flips up first
and the shutter is released afterwards
onlγ.
Intentional double exposures can be
taken as follows: After the first expo-
sure press the rewind release knob at
the bottom of the ALPA (Q Fig. 6)
，
while operating the high-speed winding
lever the second time. The film will not
advance
，
so that a second exposure can
be taken on the same frame. However
，
perfect registration cannot be guaran-
teed
，
as the take-up spool is still turning.
