Features not mentioned in this manual are explained in separate Use Manual [Basic Operation]. Before reading this manual , complete understanding and familiarization with contents of [Basic Manual] is essentially recommended. To ensure proper use , before using please read "About this product" P. Manual Organization Contents..

Focus Light.. Optical D Cable Connection Confirming useable functions. Connection example in dual strobe configuration Before starting preparation Compensation Switch Compensation Switch use External Auto shooting tips.. Reference rExposure when using strobesJ Qhl t11o er. Nikonos 5 pin type synch connector enables "electrical cable 11 connection in addition to existing "optical connection". External AutoJ mode, which does not need a strobe control signal from the camera and I ManualJ mode with 13 adjustable steps of flash output control.

By optically connecting to pre-flash type digital cameras with an "Optical D Cable" or by "wi reless connection " , the Z enables to shoot in "TTL Auto exposu re" supporting a wide range of cameras , regardless of make or model.

The Z carries more sensitive slave sensor comparing to existing models enabling highly accurate exposure control. Connecting to compact digital camera is also employ slave system to camera 's built-in strobe master strobe.

Other slave flash modes are! External AutoJ mode, which does not need a strobe control signal from th e camera , and IManualJ mode with 13 adjustable steps of flash output control. Also, it helps aim the strobe's beam axis on or near the subject. Upon activating the Focus Light Switch , the Focus Light will turn on , and upon sensing the camera's internal strobe flash , wi ll automatically turn off so no light from the 2 Focus Light is recorded in the image.

Also the Focus Light can be set to turn off automatically in about eight seconds if the Focus Light Switch is not pressed again. Clear Photo Svstem Compatible "Clear Photo System" allows the external strobe Z to be more effectively used as a Slave Strobe , and enables cleaner, higher quality images by reducing the amount of backscatter3 caused by light coming from the camera's built-in strobe illuminating suspended particles in front of the lens.

Clear Photo System was designed into the Z Also, with some camera systems the Focus Light may be recorded in the image. Refe rence G r Autom atic Flash Adjustment of External St robesJ When using external strobes, in order to automatically adjust the amount of flash output and properly expose the subject, it is necessary to calculate and control the strobe's flash duration light output amount using the following information.

Real Tim e Auto Exposu re Adjustment 2. During pre-flash , subject reflectivity measured TIL; based on this information. Extern al Auto Flas h Expos ure Adj ustment For each of these automatic flash adjustment methods to work, besides a signal instructing the external strobe to fire , following information is necessary. Also the various combinations of cameras and master strobes and external strobes must be compatible with each other 's signal transmission methods and have connection method.

Likewise , except for some dedicated land strobes for certain camera brand s, there are no external strobes yet available fully compatible of functioning with the various r Pre-flash TIL Auto Expos ure Adj ustmentJ type cameras available. For such camera to have a common un iversa l auto light adjustment system , the following are necessary.

An external strobe using these TTL metering methods of automatic light control is called a "TTL Strobe" and an extern al slave strobe set to synchronize with the master strobe's fla sh duration is ca lled a "TTL Slave Strobe".

For the purposes of this Manual, we distinguish between two types of TTL light adjustment. Refer to! Reference rnTLD - What is it? Camera 's internal strobe fires one or more small flashes before the main flash.

Reflected light from the pre-flash s is measured by the camera and used to calculate the main flash duration, for correct exposure.

In general, for "Pre-flash TTL Auto Exposure Adjustment" type camera systems, the subject reflectivity must be metered in order to ca lculate the main flash duration intensity before the shutter opens to actually reco rd the image, In order to meter the subject reflectivity, the camera fist fires one or more small flashes pre-flashes to measure the reflected light back from the subject.

And the camera ca lcu lates appropri ate main flash duration based on th e reflectivity. To determin e what kind of automatic exposure adjustment method you r camera has , check your ca mera manual and Z P. By matching strobe's [ISO sensitivity and [aperture value to came ra 's setting , the built-in light adjustment sensor meters [reflectivity of subject] in real time upon starting to flash and control flash duration by itself.

Reference r ITMaster Stroben and ITSlave StrobenJ recycle time for faster follow-up shots and reduces camera battery consumption so more images can be taken per set of batteries.

At that time, the other Slave strobe is activated by the master strobe's flash. This user manual uses following connection method terminology depending on master strobe type. Master strobe is camera 's built-in flash. The smaller of the two amounts of flash output is used con trolling the actual fla sh emission. Even under conditions unsuitable for conventional TTL Auto mode, such as when shooting a mid-range subject, full-power emi ssion will be prevented by manually setting required flash outpu t for th e subject wh ich suppress fla sh output at the preset va lue even when TTL error occurs.

This wi ll considerably reduce overexposure, and increase the number of usable images. In addition, using this mode as an alternative to Manual fla sh wi ll greatly reduce overexposure caused by inappropriate flash output settings, and will lessen a burden required for exposure calculation for every shot. Before attempting to use your strobe , it is important to understand the connection method releva nt for your situation. Transmit camera 's built-in strobe light to!

Preparing to Take lmagesJ P. There is no limitation on strobe arm selection to support wide variety of strobe arm configuration depending on a subject or an attachment lens. Wireless Connection! Transmit camera's built-in flash light to the Z via optional Wireless Connection Kit to easi ly flash in synch with master strobe. In addition to attaching single Z to camera system with specifi c strobe arm not using dedicated fiber optics to shoot in "S-TTL auto" mode, explained in detail in separate manual [ [Basic Operation 1.

Only specific strobe arm is confirmed compatible but not necessary to prepare dedicated fiber optics to provide simple and inexpensive external strobe shooting. For reference see I 1. Reference -- 4. Reference -Accessories P. Va rious kind of optical cable enables to connect either single strobe or dual strobe co nfiguration. When using as a slave strobe to another external strobe! Necessary preparation and optional parts is explai ned from next page.

Inon Z-240 Underwater Strobe (Type 4)

Control Switch: A. It will get hard to express one's image with existing underwater TTL auto strobe when a user gains experience of underwater photography. This is because that desired exposure is vary by each photographer's sensitivity and appropriate exposure is also vary depending on shooting condition like subject color etc. Manually controllable [EV Control Switch] enables you to select "real" appropriate exposure by simply dialing the switch. Compare different setting of "A" for Bit brighter , "C" for Bit dark and "C-" for Rather dark , then select "real" appropriate exposure setting. It was impossible for existing underwater TTL auto strobe to intentionally make asymmentric lighting under dual strobe configuration and only "flat" lighting was available. When using D series x 2 or Z x 2,"S-TTL Auto" side and "External Auto" side can be instantly switched over by dialing control knob enabling you to control not only darkness of shadow but can select which side of a subject you have shadow.
