Notes on Wireless Flash Control (P-TTL photography)
When using the AF540FGZ in wireless mode, the following information is transferred between the flash units attached to the camera and separated from the camera, before the flash units are discharged. Shutter release button is fully pressed. The flash attached to the camera emits a small control flash (relays the flash mode of the camera). The external AF540FGZ emits a pre-flash (verifies the state of the subject). The flash attached to the camera emits a small control flash (relays the flash output amount to the external AF540FGZ). The flash attached to the camera will emit a preflash once more after this to relay the flash duration time when HS (high-speed sync) is set. The external AF540FGZ discharges the main flash (where both flash units discharge main flashes, refer to page 44).

To change the composition, raise your finger off the shutter release button and press it halfway down again to recompose the picture. When using the AF540FGZs built-in AF spotbeam, the AF spotbeam built into the camera will not operate. The AF spotbeam on the flash unit works accurately only when mounted onto the cameras hot shoe. The flash does not discharge when using the AF540FGZ spotbeam exclusively as a focusing aid.
Wide-Angle Panel and Catchlight Panel
The AF540FGZ has a built-in wide-angle panel and catchlight panel at the top of the flash head. Execute the following if necessary.

2.Catchlight panel

A catchlight is a reflection of light source in the eyes. It usually appears as a white dot and makes the human subject look more lively. Set the bounce flash angle to 90 and get close to the subject before taking the picture.
Store the panel you are not using. When storing the wide-angle panel, push it inward while holding the catchlight panel so that it does not catch on the catchlight panel. When storing the catchlight panel, do so by pushing it inward.
Pull out both the wide-angle panel and catchlight panel.

Modeling Flash

After firing the modeling flash, slide the setting switch up (white dot). To prevent the flash tube from overheating or deteriorating, do not discharge the modeling flash more than 10 consecutive times. After the tenth time, let the flash unit rest for at least 10 minutes.

Precautions When Photographing with a Slave Flash
Be sure to set the camera as follows: - Exposure mode: M (manual) or B (Bulb Exposure) * Exposure modes other than those above are not compatible with this photographic method. Set the slave mode of the flash unit to SL 2 (refer to page 52).

Flash Effective Range

Calculating the Flash Effective Range
When setting the lens to manual f/stop, calculate the guide number at full flash with the use of flash's zoom position and ISO. Divide the resulting guide number by the aperture in use. Thus, the maximum distance is obtained. The minimum distance is obtained in dividing this max. distance by approx. 10. However, if the minimum distance obtained is 0.7m or less, the minimum distance will be 0.7m. Refer to page 82 for the guide number table.

Example:

With a 85 mm lens at f/4 and sensitivity at ISO100 For the zoom position 85mm and sensitivity at ISO100, the guide number is 54. 54 (guide number) /4 (aperture) = 13.5m (max. distance) 13.5m (max. distance) /10 = 1.35m (min. distance) Thus, flash effective range is approx. 1.35m - 13.5m.
Display of Flash Effective Range
The shooting distance parameters will be displayed on the LCD panel. Make sure that you are within the flash effective range before taking pictures. The effective flash range is displayed for the following camera and lens combinations.
Effective flash range indicator
K20D, K200D, K100D Super, K10D, K110D, K100D, *ist D series 35mm autofocus single lens reflex cameras (except for SF series) 645N2, 645N

DA, D FA, FA J, FA, F, A

D FA, FA J, FA, F, A FA645
If the maximum distance exceeds 22 meters, ( ) will blink. If the minimum distance is 0.7m or less, ( ) will blink. The flash effective range varies depending on ISO, lens aperture in use, and/or the zoom position (flash coverage angle). Keep this in mind especially when you are using a variable aperture zoom lens.

Guide Number (GN)

Guide numbers indicate flash light intensity. The larger the number, the farther you can reach with your flash. From the guide number, you can easily obtain the proper aperture setting required for an optimum exposure. Aperture (f/stop) = GN/flash-to-subject distance (m)

Depending on the camera and lens you are using, the effective flash range may be displayed. (Refer to page 81.)
