High power with Guide Number 24, wide 100 degrees circular beam angle
light distribution even without a diffuser
INON "Z-240" produces powerful guide number 24(*1) and "circular 100 degrees"(*2)coverage without a diffuser thanks to INON unique "T-shape Twin Flash" construction and optimally designed reflecting mirror / prism supporting effective light distribution even with 4 AA battery operation. This circular light distribution supports your creative and free strobe positioning with strobe arm(s) without vignetting of flash light.

(*2) 100 degrees circular beam angle without diffuser. 110 degrees circular beam angle with supplied -0.5/-1.5 diffuser
Advantage of powerful flash output when using
high-speed X synch camera
The Z-240 emits strong flash in very short period of time which solves conventional high power strobe's weak point and no power loss will happen even in fast shutter speed. In fast shutter speed, its effective power output increases at more than "approx. 30%" which is "approx. 60%" (when shutter speed is 1/250 sec.) and "approx. 90%" (1/500 sec.) comparing to Z-220 strobe.
The Z-240 supplies enough power for digital / film SLR shooters in particular shooting situation using fast shutter speed and smaller aperture setting.
Minimum recycle time of 1.6 seconds, compact body
Compact body size of the Z-240 is 99mm (outer diameter) / 100mm(depth) / 122mm(height) (*3) but its recycle time is minimum "approx. 1.6 sec." at full flash(*4). The Z-240 unique circuit components carries two sets of fundamental electrical parts (transformer: 2pcs, transistor: 4pcs) to achieve fastest recycle time in the class .

Optical / electrical connection compatible,
Carrying all well-established features of "D-2000"series
As a prosumer model, the "Z-240" is equipped with Nikonos 5 pin sync connector to connect to a conventional camera system with "electrical cable" as well as "Optical D Cable connection" compatible connecting to digital camera's built-in flash to benefit all advanced features of "D-2000" series including ["S-TTL" Auto] mode (*5)for TTL auto shooting with "Clear Photo System" compatibility. Off course you can plug use the "Z-240" to compact digital camera (transparent housing) via "Optical D Cable" for fully automatic shooting with its "S-TTL" auto mode. The highly accurate S-TTL Auto shooting accommodates with Nikon D700 / D300 /D200 / D90 / D80 which emits either single or double pre-flash. The "Z-240" supports a number of different equipment combination including upgrading your system.
(*5) Usable function may vary depending on camera system and connection method
Next generation wireless TTL
The Z-240 "Type4" successfully amplifies receiving optical signal from the slave sensor 20 times more comparing to previous Z-240 "Type3" to provide [wireless S-TTL Auto mode] without using an optical cable. With optional "Wireless Connection Kit" [Z-240 "Type4"] supports 2 way (wired/wireless) S-TTL Auto mode.
13 step Manual / 24 step External Auto
The Z-240 supports professional needs for sophisticated lighting by its 13 step[Manual mode] with 1/2 EV increments and by 24 step [External Auto] mode with 1/4EV increments which is available for digital SLR camera under electrical cable connection. The Z-240 gives you free and creative lighting.
INON unique"Advanced Cancel Circuit" benefits you with shorter recycle time (1/3) and 20% more images per battery set comparing to an external strobe carrying conventional cancel circuit (*6).
(*6) Recycle time and available number of images per battery set varies depending on camera model and setting.
High-intensity 180 lumen power LED multifunctional
Focus Light with shutter linked auto OFF function
Multifunctional Focus Light for strobe aiming and supporting focusing as well as indicator of strobe charge status making it work in synch with strobe's ready LED lamp. The Z-240 "Type 4" uses high-intensity 180 lumen power LED as Focus Light. The unparalleled brightness of the Focus Light is also usable as an independent diving light producing 180 lumen / 20 degrees coverage.
The Focus Light is automatically turns OFF in synch with shutter release. The Focus Light starts to stop emitting light at the time of "pre-flash" under "Optical D Cable Connection" with a pre-flash type digital camera, so it never recorded in an image(*7).
(*7)Focus Light may be recorded on an image depending on camera system, connection method and shooting condition.
