Auto Flash Exposure Control

Follow your flash equipment instruc-

tions for the selection of F stop for

automatic flash exposure control (in

case of the Quick Auto 310, one of

F4,

F5.6, F8; ASA 100).

* The TTL AUTO setting on the Quick

Auto 310 is exclusively for use with

the OM-2 and cannot be used with the

OM-1.

the camera-to-subject distance.

table, or guide number formula, deter-

mine the correct F stop for proper flash

exposure at the distance you found in

Step 2. Set this F stop with the camera

aperture ring. In case of the Quick Auto

310, after setting the auto/manual

switch dial to the "HI" position, read

the F number corresponding with the

planned flash-to-subject distance, using

the distance scale provided.

Turn the shutter speed ring until the

meter needle centers between the over-

and under-exposure index marks in the

camera viewfinder.

If the shutter speed is 1/60 second or

slower, you are ready to take the pic-

ture.

If the shutter speed is faster than 1/60

second, the flash will not fire if you

attempt to take the picture. Therefore,

you must readjust the exposure settings
