FLASH SYNCHRONIZATION
The Asahi Pentax has two 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 combina-
tions 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 electronic flash units
may be used.
