Fly-eye Dome Lens, High Power and 110° Underwater Beam Angle with Less Uneven Light Distribution

Yet lightweight and compact body, the Z-330 Type2 is designed to produce powerful G.N. 33 (*1). Precisely designed fly-eye 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 beam angle UNDERWATER. 
Not as like a conventional translucent white diffuser which can widen coverage while it has to sacrifice power and store heat inside, this specially designed fly-eye dome lens diffuses strobe light thanks to reflection ratio of air, acrylic and water to attain UNDERWATER beam angle 110 degree with almost all powerful output coming through. 
Furthermore, the Z-330 Type2 has overcame drawback of high-power strobe which has long flash duration and reaches to FULL power 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 Type2 can deliver full dump even at 1/1000 high shutter speed setting without cutting power.

S-TTL Auto /13 Steps Manual Flash Mode

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.

EV. Controller to Adjust Exposure of S-TTL Auto

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.

Bundled "Strobe Light Shade" to Prevent Shining Camera Lens

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.

220 lumen, Shutter Linked Auto OFF Focus Light

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.

Conspicuous Phosphorescence Back Panel, Improved Intuitive Control Dials

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.

Radiation System to Release Generated Heat Inside

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 "approx. 1.6 sec." at Full Flash

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.
(*3) With recommended Panasonic eneloop pro, BK-HCD, 1.2V, Min.2,500mAh. Recycle time based on INON test data.

Wide Variety of Dome Filters

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.

Both Optical/Electrical Trigger Supported

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

Seamlessly Work with Different Pre-flash Mode

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.
