Olympus OM-2 - Manual (Page 36)

FLASH PHOTOGRAPHY WITH AN ELECTRONIC FLASH UNIT OTHER THAN THE T32-T20
Attach the Accessory Shoe 4 to the OM-2.
Mount the electronic flash on the accessory
shoe.
If your electronic flash unit does not have a
direct contact "hot shoe", connect its syn-
chronizing cable to the camera flash socket.
Set the synchro terminal to "X" by aligning
the red dot on the FP and X selector with
the "X" indication alongside the flash socket.
Set the ASA film speed on the flash unit.
Set the shutter speed ring to 1/60 sec. or slow-
er.
Set the flash unit to the automatic or manual
setting.
Set the desired F stop on the flash unit (in the
case of auto mode), and then set the aperture
ring to this F stop. In the case of manual mode,
F stop can be determined by using the follow-
ing formula:
NOTE: Mounting the electronic flash unit on the
accessory shoe automatically completes the "X"
synchro circuit. However, there are some flash
units which do not fire unless the selector is set
to "X".
[With Quick Auto 310]
The Quick Auto 310/OM-2N (not OM-2)
combination cannot perform the TTL
("OTF") Auto flash. Use it in the Normal
Auto or Manual flash mode.
Set the camera's selector lever to "MANUAL".
