INON D200 Strobe
Expanded Underwater Coverage 110 degree by Dome Lens
Precisely designed front dome lens (*1) together with INON’s unique patented “T-shape Twin Flash” successfully manages both powerful G.N. 20 (*2) and circular 110 degree coverage UNDERWATER without sacrificing any power. Without using a diffuser, the D-200 strobe is well designed to deliver high power and wide coverage.
Not as like a conventional translucent diffuser which can widen coverage while it blocks some power and stores 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 D-200 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 D-200 can deliver full power even at 1/1000 high shutter speed setting without cutting power.

Easy to Handle Underwater, Buoyant at 4g
The D-200 strobe provides buoyancy at 4g (*3) underwater including 4 x AA eneloop batteries and Strobe Light Shade making the strobe slightly buoyant underwater. By attaching an adapter such as “Z Adapter MV” or “Z Joint” can have almost neutral buoyancy in salt water. A heavy underwater weight strobe may cause sudden strobe movement with its own weight when unclamping too much while neutrally buoyant D-200 offers comfortable strobe aiming adjustment as well as easy handling underwater.
(*3) Buoyancy measured in freshwater is about 4g/0.1oz. Calculated buoyancy in sea water is about 23g/0.8oz. 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.
