The INON Z-330 provides powerful Guide Number 33, high performance and multifunction in its compact body. Its built-in optically designed dome lens offering both high power and wide 110 degree coverage underwater without any diffuser which can sacrifice power. For digital cameras, film cameras, optical connection and sync cable connection, the Z-330 strobe supports every camera system with unparalleled features.
Yet lightweight and compact body, the Z-330 is designed to produce powerful G.N. 33 (*1). Precisely designed front dome lens (*2) together with INON's unique patented "T-shape Twin Flash" successfully manages both powerful strobe light without sacrifice any power and circular 110 degree coverage UNDERWATER.
Not as like a conventional translucent diffuser which can widen coverage while it has to sacrifice power and store heat inside, this specially designed dome lens diffuses light thanks to reflection ratio of air, acrylic and water to attain UNDERWATER coverage 110 degree with almost all powerful output coming through.
Furthermore, the Z-330 has overcame drawback of high-power strobe which has long flash duration and reaches to FULL power after start flashing in significantly short period of time.
Together with flashing system in sync with pre-flash and main flash of camera’s built-in flash, the Z-330 can deliver full dump even at 1/1000 high shutter speed setting without cutting power

INON's unique accurate auto exposure system S-TTL has been further evolved. Accuracy of exposure is advanced providing more accurate exposure. In addition, optimized high performance slave sensor never miss camera's trigger signal even with faint signal or partially damaged fiber optics cable can still trigger the strobe to offer faultless triggering.
Precised 1/2EV. increment 13 steps Manual flash control is onboard to support professional use where fine power adjustment is required to provide highly accurate lighting.
It is simple to fine-tune flash power in S-TTL Auto by dialing the EV. Control Switch on the back control panel. Adjustable range is 3 steps to increase and 6 steps to decrease. It is easy and simple to suit to personal preference or different exposure control characteristics among camera models.
The Strobe Light Shade is bundled to cut a part of strobe light to benefit not shining camera lens directly to dramatically suppress ghost or flare and backscatter when the strobe is positioned close to a lens port. The flange part rotates 360 degree. Intuitive operation and comfortable adjustment is supported even underwater with light clicks.
The built-in Shutter-linked Auto-Off Focus Light delivers 220lm brightness to support when focusing a subject and cease in synch with the shutter release then automatically turns ON again. To aim optical axis of the Focus Light in line with strobe light’s optical axis, the Focus Light has a fresnel lens in front supporting more accurate strobe aiming and improved usability as an aiming light.
Using white base high-intensity phosphorescence material for the back panel to improve visibility both during day and night dive. Also control dials are enlarged for user-friendly controllability even through thick gloves during cold water diving. The "EV. Control Switch" stops at minimum and maximum power setting telling you current switch position without seeing the switch itself.
The Z-330 strobe is equipped with circular metal heatsink carrying high thermal conductivity around light emitting area. The heatsink is directly connected to inner circuit component to release generated heat from strobe usage effectively.
Improved heat tolerance has resolved heat problem typically accompanied with powerful strobe. No stress with sudden stop of flashing to cool down.
Minimum recycle time at full flash (how fast the strobe ready lamp shines and the strobe is ready after making full flash) is approx. 1.6 sec.(*3) achieving fast recycle time even delivers powerful light.

The Z-330 strobe has a bayonet system to hold a strobe dome filter to attach/remove easily. Besides bundled Strobe Dome Filter SOFT to protect dome lens surface and soften strobe light, optional Strobe Dome Filter ND which steps down at -4EV, Strobe Dome Filter [4600K] which changes native color temperature to 4600K and Strobe Dome Filter [4900K] which changes to 4900K will be available in 2018.
Optical connection system widely supports from underwater housings for compact digital cameras to a digital SLR housings with built-in flash or SLRs housing with built-in LED trigger circuitry regardless of make or model. The strobe is equipped with Nikonos 5 pin type cable compatible sync connector to shoot in TTL Auto mode with a film camera or in Manual mode for a digital SLR housing with a bulk head (*4).
(*4) Usable function may vary depending on camera system and connection method
The high sensitive slave sensor enables wireless S-TTL Auto mode using a mirror instead of an optical cable. Attaching optional Wireless Connection Kit on the Z-330 and combined with an underwater housing via Shoe Base Set or Grip Base D4 Set creates a handy S-TTL Auto shooting set.
* Not compatible with camera's on-board wireless system such as Olympus wireless RC flash system or Nikon creative lighting system as wireless flash system differs.
Fully compatible with a camera which alters number of pre-flash between once or twice making total flashes twice or three times depending on shooting condition. The Z-330 automatically detects number of pre-flash to activate adequate program to support proper functioning of Manual as well as highly accurate S-TTL Auto mode.
INON unique Advanced Cancel Circuit benefits you with faster recycle time and more images per battery set to eliminate drawbacks when using Manual Flash mode with a pre-flash type digital camera where the built-in flash always burst full dump.
