Pentax MX User Manual

FLASH SYNCHRONIZATION
The MX has FP and X terminals on the front of
the camera body, and a separate X contact on the
built-in hot shoe. The table on the next page
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 mark on the shutter
speed dial. This indicates the highest shutter speed
at which electronic flash units may be used.
Use the hot shoe flash contact when using a shoe-
mount electronic flash which has a flash contact
on the shoe bracket.
When using the hot shoe, there is no need to plug
the flash cord into the X terminal on the front of
the body. The hot shoe flash contact turns to
'"hot" (switched on) only when you insert a shoe-
mount electronic flash. It remains "cold
(disconnected) even when using an electronic
flash with its cord plugged into the X terminal on
the body front. This eliminates the danger of
electric shocks.
