Advanced Functions ■Wireless Mode With the AF540FGZ, you can take photographs with the flash unit separated from the camera wirelessly in P-TTL mode. Combine the flash unit with the built-in flash unit of the camera or another AF540FGZ attached to the camera. ● The AF360FGZ can be used interchangeably with AF540FGZ flash units for wireless mode photography. Before photographing, confirm the following. 1. Whether your camera supports this function. ➝ Cameras that Support Wireless Mode (page 63) 2.
● Control Flash and Main Flash The purpose of the control flash of the wireless mode is to send information to the other flash unit before taking a picture. The main flash discharges at the actual time a picture is taken in the same manner as traditionally done. ● When setting up a flash unit separately from the camera, use the off-camera shoe adapter F when using a tripod, or the off-camera shoe clip CL-10 when setting up in another location such as tabletop, chair, etc.
Using the AF540FGZ in Combination with a Built-in Flash Unit Setting switch ● The AF540FGZ can be used in combination with a built-in flash unit only when used with the following cameras. *ist D, *ist, MZ-S, MZ-L/ZX-L/MZ-6, K10D (NOTE), K20D, K200D, K-x, K-7, K-m/K2000 (NOTE) However, this requires the firmware to be updated to Version 1.10 or later. Download the firmware for the K10D from the following URL, and install it on your camera. http://www.pentax.jp/english/support/download_digital.

When Using Both an AF540FGZ Attached to the Camera and a Separated Flash Unit as Main Flashes Use both flash units as main flashes (Preparation of Flash Unit Attached to Camera) 1 44 Firstly, set the wireless mode and channel of the flash unit attached to the camera, and register them on the camera. Attach the AF540FGZ to the hot shoe of the camera after turning the camera off. Set the power switch of the flash unit to (WIRELESS).
Slide the setting switch back up to the (white dot). When you turn the camera on and press the shutter release button halfway down, the channel of the flash unit is registered on the camera. (Preparation of Separated Flash Unit) 2 Next, set the channel of the separated (wireless) flash unit to the same channel as the flash unit attached to the camera. Place the other AF540FGZ in the desired position. Set the power switch of the flash unit to (WIRELESS).
Wireless High-Speed Sync Photography (Using the AF540FGZ in Combination with a Built-in Flash Unit) 1 46 Firstly, set the wireless mode and channel of the AF540FGZ, and register them on the camera. Turn the camera off and then attach the AF540FGZ to the hot shoe of the camera. Set the power switch of the flash unit to (WIRELESS). Press the wireless mode button (M/C/S) the number of times required to display SLAVE on the LCD panel.
2 When you turn the camera on and press the shutter release button halfway down, the channel is registered on the camera. Next, remove the flash unit from the camera and place it in the desired position. ● Press the flash mode button (MODE) to display (P-TTL) if the flash mode was set to the modes other than P-TTL. 3 Set the zoom position. (Refer to page 21) ● Set the zoom position with (M.Zoom) regardless of the lens you use.
(Using the AF540FGZ in Combination with another AF540FGZ) 1 48 Firstly, set the wireless mode and channel of the AF540FGZ attached to the camera, and register the channel on the camera. Turn the camera off and then attach the AF540FGZ to the hot shoe of the camera. Set the power switch of the flash unit to (WIRELESS).

■Slave With the AF540FGZ, you can take photographs with the flash unit separated from the camera wirelessly in auto or manual mode. Combine the flash unit with the built-in flash unit of the camera or another flash unit attached to the camera. Before photographing, confirm the following. 1. Whether you can use this function with the combination of your camera and the flash mode you have set. ➝ Functions Related to Each Flash Mode (page 64 - 71) 2.
5 Set the zoom position to suit the subject and place the flash unit at the desired location. ● When setting up a flash unit separately from the camera, use the off-camera shoe adapter F when using a tripod, or the off-camera shoe clip CL-10 when setting up in another location such as tabletop, chair, etc. 6 ● Do not use red-eye reduction with the camera’s flash. This will result in the AF540FGZ firing by the pre-flash.
■Slave Mode Setting To properly control the slave flash, it is necessary to set the slave mode settings. 2 seconds or more Procedure 1 2 3 Slide the setting switch up. Press the LCD panel illumination button (LIGHT) for 2 seconds or more. SL1 will be displayed. Press the select button (S) to select SL 1 or SL 2. SL 1: When photographing in wireless mode SL 2: When photographing with slave flash ● The flash will not discharge properly if the slave mode was set to the wrong mode.
■Slow-Speed Sync Photography When using a normal flash to photograph a subject in a night or evening setting, the background will appear very dark because a normal flash light cannot sufficiently light it. However, it is possible to balance both subject and background by using the flash to properly expose the foreground subject and a slow shutter speed to expose the low light background. Before photographing, confirm the following. 1.
■Bounce Flash With the AF540FGZ, you can tilt and swivel the flash head to aim at the ceiling or wall to bounce the flash before it reaches the subject. Doing so creates softer light and shadows to make the picture look more natural. Bouncing the flash will decrease the flash intensity by the time it reaches the subject. Therefore, this function is effective when photographing in P-TTL or TTL mode at short distances. 54 The bounce angle can be set to the following angles.
● A click stop is provided for each bounce angle. ● Hold the bounce lock release button and tilt the flash head downward when you set the bounce angle at -10°. ● When using bounce flash, ( ) will be displayed on the LCD panel. ● The effective flash range will blink only when the bounce angle is set at -10°. ● It is recommended to set the bounce angle at -10° to prevent uneven exposure when the distance to the subject is within 1m.
■AF Spotbeam The AF540FGZ features a built-in red spotbeam projector to assist the autofocus system in dim light and low-contrast conditions. When using the flash with autofocus camera in dark conditions, the spotbeam will be projected automatically depending on the ambient lighting conditions. This function is activated only when the camera is set to autofocus. By setting the flash mode to (SB), the AF540FGZ can be used exclusively as a focusing aid in dim light.
■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. 1 2 Pull out both the wide-angle panel and catchlight panel. 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. 2.
■Modeling Flash/Test Flash Before taking the picture, firing a modeling flash helps you to see how shadows are cast on the subject. Modeling Flash 1 2 3 Slide the setting switch down (yellow dot). Check that the flash is ready, then press the modeling button (MODELING). The flash will discharge continuously for one second. After firing the modeling flash, slide the setting switch up (white dot).
■Connecting the AF540FGZ with the Extension Cord When using the AF540FGZ separately from the camera connected by an extension cord, use the optional extension cord F5P/F5P L. Attach the extension cord F5P/F5P L to the camera using the optional hot shoe adapter FG or the optional hot shoe adapter F (refer to the diagram on the right). ● When using the AF540FGZ in combination with the built-in flash unit of the following cameras, use the hot shoe adapter FG.

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.
