Determining the aperture
The aperture setting for flash photography
is determined by dividing the guide number
of the bulb or the electronic flash unit by
the distance.
(Guide number] 56
(Distance to subject) 7
-(Aperture setting] 8
Connect the cord of the flash unit to the
synchroflash terminal (46).
Flash Synchronization Table
The M-X selecting lever is internally locked
to prevent unintentional switching of the
mode.
When switching the M-X selector, move
the lever to the right or left, until it reaches
the end while pressing the lever against the
lens barrel.
The letter X or M, which indicates the con-
tact type, should appear in the window.
* When employing electronic flash, set the M-X selector to X to syn-
chronize flash at any shutter speed.
When M-class flash bulbs are used, set the M-X selector to M to
synchronize at any shutter speed.
When F-class flash bulbs are used, set the selector to X and photo-
graph at 1/60 sec. or a slower shutter speed.
