Guide Number 33 and UNDERWATER coverage 110-degree without a diffuser.

The next generation new Z-330 strobe has built-in optically designed dome lens offering both high power and wide coverage without any diffuser which can sacrifice power. 

Powerful G.N. 33 and UNDERWATER coverage 110 degree

Yet lightweight and compact body, the Z-330 is designed to produce G.N. 33. 

Precisely designed front dome lens together with INON’s unique T shape twin flash widens powerful strobe light without sacrifice any power to accomplish UNDERWATER coverage circular 110-degrees. 

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 diffuse light thanks to reflection ratio of air, acrylic, and water to attain UNDERWATER coverage of 110 degrees with all powerful output coming through. 


Z-330 front dome lens

Furthermore, the Z-330 has overcome the drawback of high-power strobe which has long flash duration and reaches to FULL power after start flashing with a 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 

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 located to close to a lens port. 

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 and 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. 


Conspicuous Phosphorescence Back Panel and 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. 

S-TTL Auto /13 Steps Manual Flash Mode INON’s unique accurate auto exposure system S-TTL has been further evolved. The accuracy of exposure is advanced providing more accurate exposure. 

In addition, optimized high-performance slave sensor never misses camera’s trigger signal even faint or partially damaged fiber optics cable can trigger the strobe to offer faultless triggering. 

Precise 1/2EV. increments 13 steps Manal flash control is onboard to support professional use. 

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

The Z-330 is equipped with Nikonos type 5 pin sync connector as well as slave sensor to trigger optically to adopt a wide variety of camera system.
