"By far the most popular strobe from Inon. Used by many professional and non-professional underwater photographers the world over."
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.
(*1) Measurement in Air/ ISO100/m, Nominal value
(*2) 100 degrees circular beam angle without diffuser. 110 degrees circular beam angle with supplied -0.5/-1.5 diffuser.
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
The Z-240 supplies enough power for digital/film SLR shooters in particular shooting situation using fast shutter speed and smaller aperture setting.
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 .
(*3) Excluding protruded parts.
(*4) With SANYO Twiicell 2700 Series, HR-3UTG, 1.2V, Min.2,500mAh. Recycle Time / Flash Capacity based on INON test data. Actual values may vary based on battery manufacturer, battery type and age.
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
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.
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.
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
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.
