Inon D-200 Underwater Strobe

Wide, Light Weight, Super Midrange Underwater Strobe

**Note: Due to popular demand, supply of Inon strobes may be delayed - please contact us to check availability if you have a deadline.

Following latest features of the Z-330 strobe, the D-200 is designed to deliver maximum G.N. 20 and focus on optical trigger system. Built-in dome lens is optically designed to offer wide 110 degree coverage underwater without any diffuser which can sacrifice power. High performance, multi-function and friendly handling with lightest underwater weight supports your underwater photography with superior performance.

The next generation of strobes are available from Inon. Replacing the older D-2000 strobe is the Inon D-200. This strobe offers the same quality as all Inon strobes and incorporates many of the new unique features that were unveiled with the more powerful Inon Z-330 strobe.

The Inon D-200 is a midrange strobe, perfect for compact shooters and those who want something more affordable, but still high quality and full featured. It offers a powerful GN of 20 and has 100° coverage without a diffuser thanks to the new domed front port. There is a built in focus light with 220 lumen power. Improved heat tolerance with a new cicurlar metal heatsink allows for more repetitive flashes without risk of overheating. In addition it features larger controls for easier use and is much lighter than the original D-2000 at only 25.7oz (729g). Underwater weight has been improved as well with a negative buoyancy of only 4g (0.1 oz). Weight and buoyancy include strobe, Strobe Light Shade and 4 x AA Eneloop batteries.

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.

(*1) PAT. P on the dome lens system to widen underwater coverage.
(*2) Measurement in air/ ISO100・m, Nominal value.

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.


Strobe Light Shade is removable


The shade goes to any position

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.

* Note 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.

Integral Pre-flash Mode Detecting Function

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.

How long will it take for my order to arrive after I make payment?

That depends on where you live and whether we have an item in stock or not. While we do have many items in stock, we don't carry everything. If you need an item in a hurry, it's a good idea to contact us and find out if your item is in stock.

If we have it in stock, we can usually send it out as soon as we receive payment, or you can pick it up. If an item is not in stock, we'll need to order it from our suppliers, which means it can take 1-2 weeks to arrive at your door (usually closer to a week).

Sometimes delivery can take longer, if our manufacturers are out of stock, for example, but this is unusual - we let customers know as soon as possible if something like this happens.

How do you ship my orders?

We use New Zealand Post and CourierPost to ship orders. Our default is courier, though you may organise an alternative with us by contacting us directly. CourierPost aims for next day delivery nationwide between major towns and cities in the North Island. South Island delivery can take two days. If you require next-day delivery in South Island, choose the express shipping option for the South Island. If you spend over $250 get your shipping for free!

Covid-19

We hope you, your families and friends are safe and healthy during the current Covid-19 situation.

As you may know we are a small team at Sea Tech Ltd. Our team has zero close contact with people outside our bubble.

We wish to assure you, that when we begin fulfilling orders on 28 April, we will be following the government health guidelines surrounding safe operating procedures. Hygiene basics such as hand washing, coughing/sneezing protocols as well as the wearing of appropriate protective equipment such as face masks.


We are continuing to follow the regular updates to government health guidelines and initiatives regarding Covid-19.


Please do not hesitate to contact us if you wish to discuss any aspect of our delivery service via Courier Post New Zealand.

We wish you all the best during these challenging times.

When you buy something from us, the price is literally exactly what it says on the tin.

If you buy something from an overseas supplier, that is most definitely not the case. While the product might seem like a great deal on screen, it's important to understand customs and import costs.

In addition to the ticket price on an overseas purchase, whatever the exchange rate is on the day (this can fluctuate wildly - trust us, we know), there are also tariffs, GST and border processing fees. This can easily add upwards of 25% to the ticket price. Items costing over NZ$1000 also incur import entry transaction fees.

In addition to these extra costs, Customs clearance can also cause delays. Sea Tech has been importing for years - we've got this down to a fine art, and we've built relationships with customs that help our items clear quickly.

By buying from Sea Tech, you avoid all the headaches, delays and extra costs. We handle all this stuff for you, so you don't even have to think about it.
