Flash synchronization The Honeywell Pentax has two sets of terminals -FP and X. The table below shows which flash contact, which shutter speed and which flash bulb may be combined for maximum lamp efficiency. Unless these combinations are rigidly followed, there will be a failure in flash synchronization. Note the "X" setting is exactly at the 60 marked on the speed dial. This indicates the highest shutter speed at which Honeywell Strobonars or other electronic flash units may be used.

has
two
sets
of
termi-
nals
—FP
and
X.
The
table
below
shows
which
flash
contact,
which
shutter
speed
and
which
flash
bulb
may
be
combined
for
maximum
lamp
efficiency.
Unless
these
combinations
are
rigidly
followed,
there
will
be
a
failure
in
flash
syn-
chronization.
Note
the
"X"
setting
is
exactly
at
the
60
marked
on
the
speed

This
indicates
the

flash
units
may
be
