Cautions Regarding Batteries  
This flash unit uses four AA alkaline, lithium, or nickel metal hydride batteries. Do not use any other type of  
battery. The flash unit may not be able to operate correctly or demonstrate sufficient performance, or the flash  
unit itself may generate heat, depending on the type of batteries used.  
AA alkaline and lithium batteries themselves are not rechargeable. Also, do not dismantle the batteries. Trying  
to recharge or dismantle these batteries may cause an explosion or leakage.  
When changing batteries, do not mix batteries of different manufacture, type and capacity.  
Do not insert the batteries with the positive (+) and negative (-) terminals the wrong way around. Incorrect  
insertion may lead to an explosion or fire.  
Battery performance may temporarily be hindered in low temperatures. Batteries should be kept warm in  
temperatures below freezing for proper performance.  
If you do not intend to use the flash unit for an extended period of time, remove the batteries. Leaving the  
batteries in may cause damage to the flash unit due to leakage etc.

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.  
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.  
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.  
Auto flash (A)  
The built-in flash metering sensor adjusts the flash  
output automatically. Use with cameras that are not P-  
TTL or TTL Auto flash compatible. Refer to page 28 for  
instructions on how to use this flash mode.  
Functions Related to Each Flash Mode  
(page 64 - 71)  
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.

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.  
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.  
Functions Related to Each Flash Mode  
(page 64 - 71)  
3. Restrictions for the use of each sync mode.  
Sync Mode Restrictions (page 72 - 76)  
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.

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. Whether your camera support this function  
Cameras that Support Slow-Speed Sync Mode  
(page 64)  
2. Whether you can use this function with the  
combination of your camera and the flash mode  
you have set.

The bounce angle can be set to the following angles.  
Rightward: 0°, 30°, 60°, 90°, 120°, 150°, 180°  
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.

manual and other references are recommended.  
P-TTL, TTL Auto Flash Photography  
The amount of reflective light will change according to  
the condition of the reflective surface, angle, and  
distance. However, with TTL auto flash units bounce  
flash photography can be relatively easily done.  
Confirm the flash status indicator in the viewfinder or  
the auto check display in the LCD panel when taking  
pictures.

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 AF540FGZ’s 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 camera’s  
hot shoe.  
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.  
The flash does not discharge when using the  
AF540FGZ spotbeam exclusively as a focusing  
aid.  
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.

Wide-Angle Panel and Catchlight  
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.

Cameras Capable of Modeling Flash or  
Test Flash Photography Using the Camera  
Button  
Modeling Flash/Test Flash  
Before taking the picture, firing a modeling flash helps  
you to see how shadows are cast on the subject.  
With the following cameras, a button on the camera  
can be used instead of the modeling button  
(MODELING) or the test button (TEST). This operation  
can be carried out with either an attached flash unit or a  
wireless flash unit. For information on how to arrange  
this, refer to the operating manual for the camera.  
Modeling Flash  
Slide the setting switch down (yellow dot).  
1
Check that the flash is ready, then press the  
2 modeling button (MODELING). The flash will  
discharge continuously for one second.  
*ist D: You can use the OK button. (Refer to "Custom  
Function Chart" in the camera's operating  
manual.)  
After firing the modeling flash, slide the setting  
3 switch up (white dot).  
*ist:  
You can use the flash pop-up button. (Refer to  
"Setting the Custom Function" in the camera's  
operating manual.)  
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.  
MZ-S: You can use the LCD illuminator button. (Refer  
to "PENTAX Functions" in the camera's  
operating manual.)  
Test Flash  
Check that the flash is ready, then press the test button  
(TEST). The test flash will discharge.

Flash Effective Range  
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.  
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.  
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.

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.

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

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 manufacturer’s  
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 manufacturer’s 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.
