Following the latest features of the Z-330 flash, the D-200 underwater flash is designed for a maximum guide number of 20 and an optical trigger system. The built-in dome lens is optically designed to provide wide 110-degree underwater coverage without a diffuser that can affect performance. High performance, multi-functionality and user-friendly handling with the lightest underwater weight support your underwater photography with superior Performance. Extended underwater coverage 110 degrees through dome lens The precisely designed front dome (*1) together with INON's unique patented "T-Shape Twin Flash" successfully creates both a strong guide number of 20 (*2) and circular 110 degree coverage underwater without sacrificing power. Without the use of a diffuser, the D-200 flash is well designed to deliver high power and wide coverage. Unlike a conventional translucent diffuser that can widen coverage while blocking some of the power and trapping heat inside, this specially designed dome lens diffuses light thanks to the reflective ratio of air, acrylic and water to achieve 110 degrees of UNDERWATER coverage with almost all of the powerful output passing through it. In addition, the D-200 has overcome the disadvantage of the high-power flash, which has a long flash duration and reaches full power in a significantly short time after starting the flash. Together with the flash system synchronised with the pre-flash and main flash of the camera's built-in flash, the D-200 can deliver full power even at a high shutter speed of 1/1000 without reducing output. (*1) PAT. P on the dome lens system to extend underwater coverage. (*2) Measurement in air / ISO100?m, nominal value.   Easy to handle under water, buoyancy only 4 grams The D-200 strobe light provides buoyancy at 4 g (*3) underwater, including 4 x AA eneloop batteries and Strobe Light Shade, making the strobe light easily buoyant underwater. By attaching an adapter such as "Z Adapter MV" or "Z Joint", the buoyancy can be almost neutral in salt water. (*3) The buoyancy measured in fresh water is about 4g. The calculated buoyancy in seawater is about 23g. Includes 4 x "eneloop" batteries and Strobe Light Shade. S-TTL automatic /13 power levels in manual flash mode Proven and reliable INON's unique, super-accurate automatic exposure system "S-TTL" Auto mode (patented) is on board to support simple and solid underwater photography with balanced exposure. What's more, even if the signal is weak or the fibre optic cable is partially damaged, the optimised, high-performance slave sensor never misses the camera's trigger signal so as not to hinder you with fickle flashes. Manual flash control with precise 1/2 f-stops is also built in to support professional use when fine-tuning of power is required for high-precision lighting. Power controller for setting the exposure of the S-TTL automatic system Fine-tuning the flash output in S-TTL auto mode is easy by selecting EV. control switch on the back of the control panel. The setting range can be increased in 3 steps and decreased in 6 steps. It is simple and straightforward to adjust to the intended exposure or the different exposure control characteristics of different camera models. Bundled "flash baffle" to prevent illuminated camera lens The "flash hood" (included) "cuts off" a portion of the flash light to dramatically reduce flash or ghosting by not directly illuminating the camera lens. It also prevents floating particles when a flash is positioned near or in front of the lens port, as the water between the port and the subject is less illuminated. The flange part can be rotated 360 degrees. Intuitive operation and comfortable adjustment is supported by easy clicks even under water during shooting.   Trigger-coupled auto OFF focus light with 220 lumens The built-in "Shutter-linked Auto-Off Focus Light" provides 220 lumens of brightness that assists the camera in focusing on a subject and stops in sync with the shutter release, then automatically turns back on. To align the optical axis of the focusing light with the optical axis of the flash, the focusing light has a Fresnel lens in front of it, which supports more accurate aiming of the flash and better usability as an aiming light. Eye-catching fluorescent back panel - Improved intuitive controls Use of high-intensity white-based phosphorescent material for the back panel to improve visibility during both day and night dives. The control buttons are also enlarged to allow user-friendly control even through thick gloves when cold-water diving. The "EV. Control Switch" stops at the minimum and maximum power setting and shows you the current switch position without seeing the switch itself. Radiation System for releasing the generated heat inside The D-200 underwater flash is equipped with a circular metal heat sink that has high thermal conductivity around the light-emitting surface. The heat sink is directly connected to the inner circuit component to effectively dissipate the heat generated when using the underwater flash. Improved heat tolerance has solved the heat problem normally associated with a powerful underwater flash. No stress with sudden stop of the flash to cool down. Minimum recycling time "approx. 1.6 sec." at full flash output The minimum repetition time at full flash (how quickly the flash-ready lamp lights up and the flash is ready after full flash) is approx. 1.6 sec(*3), giving a fast repetition time that even provides strong light. (*3) With recommended Panasonic "Eneloop Pro", BK-HCD, 1.2V, Min.2.500mAh. Recycling time based on INON test data. Large selection of dome filters The Z-330 underwater flash has a bayonet system to accept a dome flash filter, which is easy to attach/remove. In addition to the bundled "Strobe Dome Filter SOFT" for protecting the dome lens surface and softening the flash, the "Strobe Dome Filter ND", which drops at -4EV, the "Strobe Dome Filter [4600K]", which changes the native colour temperature to 4600K, and the "Strobe Dome Filter [4900K]", which changes to 4900K, are optionally available. Simple yet secure optical cable connection The INON optical connection system is flood-free and provides a simple but reliable connection between flash unit and camera system, including compact digital camera housings, housings for digital SLR cameras with built-in flash or SLR housings with built-in LED trigger circuit, regardless of brand or model. Integrated wireless TTL The high-sensitivity slave sensor enables wireless S-TTL auto mode using a mirror instead of an optical cable. Attaching the optional wireless connection kit to the D-200 and combining it with an underwater housing via the Shoe Base or Grip Base Set D4 creates a practical S-TTL auto shooting kit. * Not compatible with the camera's wireless on-board system such as Olympus' wireless RC flash system or Nikon's creative lighting system as the wireless flash system is different. Integrated pre-flash mode detection function Fully compatible with a camera that changes the number of pre-flashes between once and twice, and flashes two or three times in total depending on the shooting condition. The D-200 automatically detects the number of pre-flashes to activate a suitable programme that supports both manual and high-precision S-TTL auto modes. The unique INON Advanced Cancel Circuit benefits you with faster recycle time and more images per set of batteries to eliminate disadvantages when using manual flash mode with a digital camera with pre-flash, where the built-in flash always fires at full.

High power with Guide Number 20 Wide 100° circular distribution even without a diffuser Patented T-shape Twin Flash structure produces guide number 20 (*1) with wide circular beam angle 100° even without a diffuser to deliver strobe light wide area. The beam coverage increases to 110° with a diffuser. This ideal circular strobe light distribution does not require locating the strobe parallel to camera to support sophisticated and flexible angled lighting with strobe arm.  (*1) Measurement in air/ISO100・m, Nominal value   Precise S-TTL Auto mode works with any make The D-2000 offers highly accurate S-TTL Auto mode by transmitting built-in flash light to an external strobe regardless of make or model of camera. The S-TTL Auto does not require any complicated setting.

In addition to the reliable and super-accurate S-TTL auto mode, the 12-step manual mode is equipped to support professional use. Other features include the EV. Controller for fine-tuning when shooting in S-TTL auto mode and the automatic switching function to adapt to different pre-flash modes (single or double pre-flash) of the digital camera are also integrated. (*2) Measurement in air /ISO100?m, nominal value (*3) When using "eneloop" or other compatible NiMH batteries.   Integrated wireless TTL capability The S-2000 underwater flash has a high-sensitivity slave sensor that is 100 times more sensitive than the slave sensor of the D-2000 Type 3 flash and successfully enables support for S-TTL wireless auto flash without the use of a D optical cable. The sensitivity of the slave sensor also dramatically extends the sync range of manual flash operation. The package includes a Wireless Connection Kit that optimises the built-in flash light reception on the slave sensor. Wireless S-TTL auto flash is easy to use by simply attaching the flash to a compatible underwater housing via the INON connection kit or the D4 handle base. You can photograph a vivid underwater world with a powerful external flash holding a rig with one hand. Using the D-cable optical connector ensures more reliable flash sync in challenging conditions with bright ambient light such as just below the surface.   Unlimited expandability with optical cable system The S-2000 underwater flash from Inon is equipped with a plug holder on the front to receive the flash's TTL signal. An S-2000 flash unit can be connected to a maximum of two flash units via optical cables and operate them in [S-TTL Auto mode]. This optical cable system offers the advantage that you can easily supplement the [S-TTL Auto] flash mode by connecting an optical cable to receive the S-TTL control signal from your camera system. This expansion option makes an underwater studio with perfect lighting feasible.   Natural colour even with a diffuser The beam angle without diffuser is 105º x95º, which increases to a circular 110º with the supplied -0.5 white diffuser for S-2000. The diffuser is made of specially manufactured material so as not to change the colour of the flash light, where the colour temperature of the flash light only drops by 100K (Kelvin). You can have the same colour tone between macro shots without the diffuser and wide angle shots with the diffuser to widen the flash beam angle.

The Dome Lens Extension IIIG uses a multi-coated optical glass lens that provides high image quality under all shooting conditions. Dome lens extensions features a multi-coated optical dome element that effectively suppresses flare/ghost images and provides a sharp image with stable contrast even when shooting in bright and clear water. Installing this super wide-angle option on the UWL-95 C24 increases the underwater angle of view to approximately 141° and reduces the focusing range at a minimum focusing distance of 0 cm to bring the subject into focus on the lens surface. Verdict: Superior ultra-wide dome lens suitable for a wide range of shooting conditions, not only for wide seascapes but also for Close Focus Wide Angle (CFWA). The dome lens extensions IIIA and IIIG use the same lens tube, so that other dome material can be used if necessary (e.g. when replacing damaged original dome material). NOTE: The IIIA/G dome lens unit must be used with the UWL-95 C24 series underwater lens and cannot be used as a standalone lens.

Dedicated super dome option for UWL-S100 ZM80 wide conversion lens to increase underwater view angle by simply attached it on the compatible wide conversion lens to provide "more wide angle image" and "more close-up image" comparing to sole use of the UWL-S100 ZM80 underwater.   Maximum angle of view underwater is [149.8°] with "UWL-S100 ZM80" wide conversion lens .   Unique optical design allows to shorten minimum focal distance with super wide view angle thus effective for ultra wide macro imaging and capturing clear image even in poor visibility condition.   The Dome Lens Unit II is specially designed for the UWL-S100 ZM80 wide conversion lens making it compact and lightweight.   Its optical glass has anti-reflection multi-coating and antifouling coating on its inner surface to suppress flare and ghost and enhance durability while outer surface has hard coating to prevent accidental scratches.   The packaged protector shades unnecessary light to get clear image in addition to prevent accidental damage on the lens surface. Usage of the Dome Lens Unit II for UWL-S100 ZM80 *This product cannot be used by itself and must be used with compatible INON wide conversion lens.   *As same as using UWL-S100 ZM80 itself, set to zoom position 80mm (35mm film equivalent) until no vignetting is observed. Do not zoom beyond necessity as it will sacrifice view angle not to appreciate optimal performance of the lens.   *Generally, set Macro Mode to [ON]. However, for some cameras, depending on the particular focus range and aperture capabilities, some subjects at farther distances may not be in focus. In such cases, set Macro Mode to [OFF].

Successfully delivers underwater angle of view approx. 141° when using with a digital camera equipped with a large (i.e. 1.0 inch) image sensor. Smaller size comparing to the previous Dome Lens Unit II. The Dome Lens Unit IIIA Using High Transparency Optical Acrylic Material High transparency and lightweight optical acrylic dome provides quality image on a level with that of optical glass dome. Acrylic is better tolerated than polycarbonate to discoloration by inevitable ultraviolet rays outdoors or scratches during long-term usage assuring underwater use. The acrylic version is budget-friendly so would be good choice for those thinking to start wide angle photography. Optical Multi-coating Dramatically Improves Performance in Backlit Situation Both acrylic and glass version are finished with optical multi-coating which suppresses flare/ghosting effectively when shooting in bright and clear water or using back lighting technique to produce clear and quality images with appropriate contrast. Maximum Underwater Angle of View 141° The UWL-95 C24’s native underwater coverage approx. 95° will further increase to approx. 141° by installing the Dome Lens Unit III. A compact digital camera equipped with a large 1.0-type image sensor fitted with this optical combination enables to deliver vivid wide angle imaging as like an action camera without vignetting. *Rated angle of view is approximate value. No Vignetting at Zoom Wide End 24 mm Comparison shots by Sony DSC-RX100M5A at wide end (24 mm) Dome Lens Unit II Dome Lens Unit III The Dome Lens Unit III is optimally designed for a compact digital camera equipped with a large 1.0-type image sensor enabling to shoot at wide end 24mm/f1.8 without vignetting.
