Flash Synchronization - Honeywell PENTAX SPOTMATIC IIa Operating Manual

Flash synchronization
The Spotmatic Ila has FP and X terminals at the front of the camera body,
and a separate X flash contact on the built-in hot shoe. The table below shows
which flash contact, which shutter speed and which flash bulb may be com¬
bined 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 electronic flash units may be used.
The hot shoe X flash contact may be used with hot shoe Strobonars and
Auto/Strobonars or any other electronic flash or flash gun that fits the
built-in hot shoe of the Spotmatic lla.
IV/ien not using these terminals, keep the plugs inserted in the terminals.
