Using the Flash Modes

The AF540FGZ has the following flash modes. Select the mode best suited for the subject. Before photographing, confirm the following. 1. Whether your camera supports the desired flash mode. Cameras that Support Each Flash Mode (page 60) 2. Whether you can use the desired function with the combination of your camera and the flash mode you have set. Functions Related to Each Flash Mode (page 64 - 71)

TTL auto flash (TTL)

Based on the amount of light reflected off the film of the camera, the camera adjusts the flash output automatically to obtain a correct exposure. Refer to page 27 for instructions on how to use this flash mode.

Auto flash (A)

The built-in flash metering sensor adjusts the flash output automatically. Use with cameras that are not PTTL or TTL Auto flash compatible. Refer to page 28 for instructions on how to use this flash mode.

Manual flash (M)

When the camera is set to manual exposure, manual flash can be set to suit the subject distance and aperture. The manual flash output can be set to 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, or 1/64. Refer to page 30 for instructions on how to use this flash mode.

P-TTL auto flash (P-TTL)

A pre-flash is discharged before the main flash so that the multi-segment metering sensor can measure the subject's distance, brightness, brightness difference, backlit condition, etc. The data obtained is incorporated to set the output of the main flash. This mode obtains more accurate results than with the conventional TTL mode. Refer to page 26 for instructions on how to use this flash mode.

P-TTL Auto Flash

Effective flash range
Set the sync mode switch to leading curtain sync ( ), trailing curtain sync ( ), or contrast-control ( ), according to the subject. (Refer to page 32.) After turning the power (ON), the setting will be (P-TTL) and (A.Zoom).
Refer to page 25 for the features and conditions of use of this flash mode.
Turn on the flash unit. Press the flash mode button (MODE) until (P-TTL) is displayed on the LCD panel.
Confirm that the subject is within the effective flash range and the ready lamp is lit. Then take a picture. In the following cameras, if the correct flash output is obtained, the flash mode indicator and ( ) in the viewfinder will blink. *ist, MZ-S, MZ-L/ZX-L/MZ-6 For details, refer to Auto Check Display on page 11. The correct flash output is obtained in P-TTL auto mode only when the flash unit is used with autofocus lenses. If necessary, an exposure compensation amount can be set between +1.0 to -3.0 steps in 0.5-step increments. (Refer to page 18.)
Set the zoom position. (The setting method differs according to your camera and lens. Refer to page 21.)

Manual Flash

Press the flash mode button (MODE) to display (M) (1/xx) on the LCD panel. You can set the flash output from 1/1 to 1/64. See page 18.
Turn on the power switch.

Example: If the flash zoom position is 50mm, subject distance (between the AF540FGZ and subject) is 4 m, and sensitivity is ISO 100, the calculation will be as follows: With flash output (1/1), the Guide No. will be 45 (according to the Guide No. table). Aperture = Guide No. 45 / Subject distance 4 m = 11.25 Approx. 11 (f/Stop) Refer to page 82 for the guide number table.
Confirm that the subject is within the effective flash range and the ready lamp is lit. Then take a picture. In the following cameras, if the correct flash output is obtained, the flash mode indicator and ( ) in the viewfinder will blink. 645, LX, MZ-M/ZX-M For details, refer to Auto Check Display on page 11.

Using the Sync Mode

The AF540FGZ has the following sync modes. Select the mode best suited for the subject. Before photographing, confirm the following. 1. Whether your camera supports the desired sync mode. Cameras that Support Each Sync Mode (page 62) 2. Whether you can use the desired sync mode with the combination of your camera and the flash mode you have set. Functions Related to Each Flash Mode (page 64 - 71) 3. Restrictions for the use of each sync mode. Sync Mode Restrictions (page 72 - 76)
Trailing Curtain Sync Mode
In this sync mode, the flash is discharged at the instant the second curtain begins its travel. This mode will freeze the subject with a blur appearing after the subject under a slow shutter speed condition. Refer to page 33 for instructions on how to use this sync mode.

High-Speed Sync Mode

This sync mode will enable flash synchronization with shutter speeds faster than the X-sync speed. Since there is no sync speed limitation, high-speed sync is effective for fill-flash in daylight. Refer to page 34 for instructions on how to use this sync mode.
Contrast Control Sync Mode
This sync mode enables you to photograph with multiple flash units, utilizing the difference of the light intensity of each flash unit. The ratio of flash light intensity between the flash unit set to this sync mode and the other flash unit is 1:2. Refer to page 36 for instructions on how to use this sync mode.
Leading Curtain Sync Mode
This is the most commonly used sync mode. In this mode, the flash discharges at the instant the first shutter curtain completes its travel. You can use this mode with the shutter speed set to the X-sync speed or slower. Refer to page 33 for instructions on how to use this sync mode.

Refer to page 32 for the features and conditions of use of this sync mode. Refer to Connecting the AF540FGZ with the Extension Cord on page 59 on using the AF540FGZ detached from the camera.
Set the zoom position. (The setting method differs according to your camera and lens. Refer to page 21.) If the AF540FGZ is much closer to the subject than the flash unit to be used in combination, use (M.Zoom) to set the zoom position to a shorter lens focal length.
Turn on the power switch. Set the sync mode switch to contrast-control ( ).
Turn on the flash units to be used in combination.
If the camera's built-in flash unit is part of the combination, pop up the built-in flash. Confirm that the subject is within the effective flash range and the ready lamp is lit. Then take a picture.

With a single flash

With contrast control sync flash
If you are using a single flash unit, you can only perform leading curtain sync photography when the sync mode switch is set to contrast-control ( ).

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. 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) 3. Whether the slave mode is set to SL1. Slave Mode Setting (page 52)
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).
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. Keep the distance from the built-in flash unit and AF540FGZ to the subject within 4 meters.

Using the AF540FGZ Spotbeam Exclusively as a Focusing Aid
1.Set the power switch to the (ON) position. 2.Press the flash mode button (MODE) to select (SB). 3.Set the camera to the autofocus mode. 4.Press the shutter release button halfway down to let the AF spotbeam discharge. The AF spotbeam does not work in bright light conditions. If the In-focus indicator does not light up in several seconds, it means that the subject is hard to autofocus. In this case, use the manual focus mode to focus on the subject.
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.
Catchlight panel Wide-angle panel

1.Wide-angle panel

The wide-angle panel expands flash coverage angle for the following lenses. The flash zoom position will be fixed at the same position as the focal length of the lens. 13 mm for digital camera, 20 mm for 35 mm camera, 35mm for 645 camera, 55mm for 67 camera.
Modeling Flash/Test Flash
Before taking the picture, firing a modeling flash helps you to see how shadows are cast on the subject.

No refunds will be made on repairs performed by non-authorized PENTAX service facilities. Procedure During 12-month Warranty Period Any PENTAX which proves defective during the 12-month warranty period should be returned to the dealer from whom you purchased the equipment or to the manufacturer. If there is no representative of the manufacturer in your country, send the equipment to the manufacturer, with postage prepaid. In this case, it will take a considerable length of time before the equipment can be returned to you owing to the complicated customs procedures required. If the equipment is covered by warranty, repairs will be made and parts replaced free of charge, and the equipment will be returned to you upon completion of servicing. If the equipment is not covered by warranty, regular charges of the manufacturer or of its representatives will apply. Shipping charges are to be borne by the owner. If your PENTAX was purchased outside of the country where you wish to have it serviced during the warranty period, regular handling and servicing fees may be charged by the manufacturers representatives in that country. Notwithstanding this, your PENTAX returned to the manufacturer will be serviced free of charge according to this procedure and warranty policy. In any case, however, shipping charges and customs clearance fees are to be borne by the sender. To prove the date of your purchase when required, please keep the receipts or bills covering the purchase of your equipment for at least a year. Before sending your equipment for servicing, please make sure that you are sending it to the manufacturers authorized representatives or their approved repair shops, unless you are sending it directly to the manufacturer. Always obtain a quotation for the service charge, and only after you accept the quoted service charge, instruct the service station to proceed with the servicing.
