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

Precisely designed fly-eye dome lens (*1) together with INON’s unique patented “T-shape Twin Flash” successfully attains Guide Number 20 (*2), underwater beam angle 110 degree and even light distribution. The D-200 Type2 supports both power and wide underwater beam angle without sacrifice strobe output.

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 D-200 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.

(*3) Buoyancy measured in freshwater is about 12g/0.4oz. Including 4 x “eneloop” batteries and Strobe Light Shade.

S-TTL Auto /13 Steps Manual Flash Mode

Proven and reliable INON’s unique super accurate auto exposure system “S-TTL” Auto mode (patented) is onboard to support easy and solid underwater shooting with appropriate 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 not to bother you with unstable flashing. Precise 1/2EV. increment 13 steps Manual flash control is onboard as well 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 your intended exposure or different exposure control characteristics among camera models.

Bundled “Strobe Light Shade” to Prevent Shining Camera Lens

The “Strobe Light Shade” is bundled as standard accessory to cut a part of strobe light to benefit to dramatically suppress flare or ghost by not shining camera lens directly and backscatter when a strobe is positioned to vicinity or ahead of lens port by blocking light between lens port and subject not to shine suspended particles.
The flange part rotates 360 degree. Intuitive operation and comfortable adjustment is supported with light clicks even underwater while you shoot.

220 lumen, Wide-spread 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 (U.S. Patented). A fresnel lens is fitted on the front of the built-in LED light to align the light with the optical axis of the strobe. In combination with the front fly-eye dome lens, the beam angle has been greatly increased while minimizing the loss of light intensity. By illuminating the subject over a wide area, it greatly improves the usability as a target light.

Conspicuous Phosphorescence Back Panel

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 D-200 strobe Type2 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 effectively. Improved heat tolerance has resolved heat problem typically accompanied with powerful strobe. No stress with abrupt stop of flashing to cool down.

Minimum Recycle Time “approx. 1.3 sec.” at Full Flash

Minimum recycle time at full flash (Time from full flash to strobe ready lamp on and ready to fire.) is approx. 1.3 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 D-200 strobe Type2 has a bayonet system to hold a strobe dome filter to attach/remove easily. Besides bundled “Strobe Dome Filter SOFT” which protects 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 are available for creative lighting needs.

The Strobe Dome Filter SOFT installed on the Z-330.

Easy yet Secure Optical Cable Connection

INON optical connection system is flood-free and provide simple yet reliable connection between strobe and camera system including compact digital camera housings, housings for digital SLR camera with built-in flash or SLR housings with built-in LED trigger circuitry regardless of make or model.

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 D-200 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.
