Lens iris

<AUTO>

In this mode, the flash light intensity is controlled automatically according to the lens iris (F) setting.

ISO speed

1. Turn dial A to adjust the ISO speed.

2. Adjust Zoom according to the focal length of the lens.

3. Turn dial B according to the lens iris (F).

If the camera setup (ISO speed and lens iris (F)) does not match one of the usable ISO speed/lens iris (F) combinations, the ISO and F indicators blink to alert you. In this case, change the camera setup (ISO speed and/or lens iris (F)).

Lens iris (F)

■Light control range in AUTO mode

In this mode, the flash is emitted according to the guide number (GN) setting.

Guide number (GN)

1. The control panel shows the current guide number (GN)

together with the light intensity ratio. Light intensity ratio: Ratio of emitted light intensity with respect to the intensity at full emission.

2. Adjust Zoom according to the focal length of the lens.

3. Turn dial A to set the guide number (GN).

(This is also possible by turning dial B.)

Light intensity ratio

How to determine the lens iris (F) and guide number (GN)

1. When the shooting distance and lens iris are already

determined: Determine the guide number (GN) with the following formula and set the GN on the FL-50.

Guide number (GN) =

Lens iris (F) x Shooting distance (m)

ISO speed coefficient

2. When it is necessary to determine the lens iris (F):

Determine the lens iris (F) with the following formula and set F on the FL-50.

Lens iris (F) =

Guide number (GN) x ISO speed coefficient

Shooting distance (m)

The above table shows the light control ranges in the off-flash condition. The displayed nearer value is 0.6 or more when the light emission section faces the front and 0.5 or more when it faces downward.

4.When flash activation has been performed correctly,

the AUTO CHECK lamp blinks for about 5 seconds after the shutter is released.

Memo:

By selecting an ISO speed and lens iris (F) different from those set on the camera, the light intensity can be adjusted in 1/3 steps.

Test flash activation

Memo:

Flash activation can be tested before actually releasing the shutter. Press the Test button for test flash activation. The light control is OK when the AUTO CHECK lamp blinks for about 5 seconds after the test flash activation. If the lamp does not blink, change the lens iris (F), ISO speed, subject distance, etc.

• The light check by means of test flash activation is possible only in the AUTO mode.
