The INON Z-330 provides powerful Guide Number 33, high performance and multifunction in its compact body. Its built-in optically designed dome lens offering both high power and wide 110 degree coverage underwater without any diffuser which can sacrifice power. For digital cameras, film cameras, optical connection and sync cable connection, the Z-330 strobe supports every camera system with unparalleled features. Dome Lens Provides Both Powerful Light and Underwater 110 degree Coverage Yet lightweight and compact body, the Z-330 is designed to produce powerful G.N. 33 (*1). Precisely designed front dome lens (*2) together with INON's unique patented "T-shape Twin Flash" successfully manages both powerful strobe light without sacrifice any power and circular 110 degree coverage UNDERWATER. 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 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 Z-330 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 Z-330 can deliver full dump even at 1/1000 high shutter speed setting without cutting power (*1) Measurement in air/ ISO100·m, Nominal value (*2) PAT.

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, 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. Conspicuous Phosphorescence Back Panel - 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. 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 Z-330 strobe 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 from strobe usage effectively. Improved heat tolerance has resolved heat problem typically accompanied with powerful strobe. No stress with sudden stop of flashing to cool down. Minimum Recycle Time "approx. 1.6 sec." at Full Flash Minimum recycle time at full flash (how fast the strobe ready lamp shines and the strobe is ready after making full flash) is approx. 1.6 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 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 Optical connection system widely supports from underwater housings for compact digital cameras to a digital SLR housings with built-in flash or SLRs housing with built-in LED trigger circuitry regardless of make or model.

NEW, YS-D3 MKII MODEL Sea&Sea has now updated its flagship YS-D3 strobe to the YS-D3MKII. The new updates enhance TTL shooting and third-party optical converter compatibility while still retaining all the great features, such as a 33 Guide Number, wide Beam Angle and broad flash distribution of the original D3 The new MKII model will be a “running change” update, that is, the product number (#03123), will remain the same. Features of the YS-D3MKII model Newly developed software enables compatibility with existing and previous Sea&Sea optical converters. TTL shooting with the YS-D3MKII can now be enjoyed using the YS-D2 position on the S&S optical converter. A newly designed circuit improves the accuracy of TTL light intensity with compact cameras and also provides greater compatibility with third-party Optical TTL converters. The design of the light intensity adjustment dial and mode switch has been revised for better useability in all diving environments.  The difference can be easily recognized from the outside by the MKII label on the side of the unit and the new control knobs on the rear. High Performance U/W-Strobe Newly designed circuitry and light-emitting unit produces powerful guide number of 33. In addition, a high precision aspherical optical troidal lens has been fitted over the two flash tubes to disperse an even light from the center to the edge. The strobe`s beam angle will increase to 110°by attaching the standard accessories Diffuser. When the optional Dome diffuser is attached, beam angle will increase to as wide as 150(TBD) In order to avoid misunderstanding, the YS-D3 guide number (GN) and the beam angle are based on measurements taken on land (not underwater)  Some competitors will often state a GN measured on land and the beam angle in water, for example a GN 33 and beam angle of 110 degrees. However, this GN 33 value is based on a beam angle of 60~70 degrees. The beam angle may be expanded in water by a dome effect, however the GN in water is significantly lower than the value measured on land.  Note: A land-based strobe that uses the same four AA batteries as the YS-D3 may provide a notation that the GN is 60, but these measurements are taken under the condition that the focal length is equivalent to 200 mm (= beam angle 12 °). When the beam angle becomes narrower, the brightness of the illuminated area increases due to the light-collecting effect. Aspherical optical troidal lens Superior consecutive firing capability to capture those critical moments. The YS-D3 utilizes larger capacity condensers compared with those used on competing strobes. In addition, the D3 is also equipped with a newly designed charging circuit. As a result, the YS-D3 will fire at GN16 continuously without any interval time. Even when the strobe is fired at GN22, the strobe will fire again within a mere 0.8 seconds.  When the YS-D3 is fired at Guide Number over 22, a two-stage ready-to-fire signals will be issued. For instance, after the strobe fires at full power of GN33, the strobe will inform you both visually and audibly when the condenser is charged to fire at GN22. Then, when the condenser is charged enough to fire at GN33, another different signal will be issued. This design allows you to release more shutters in scenes where you want to shoot as many pictures as possible, maximizing shooting intervals between scenes Target light with increased power incorporating a uniquely designed aluminum heat diffuser, the target light is now powerful enough to be used as a dive light.?About 4 times brighter than YS-D2? Various accessories available for all underwater imaging experiences Dome diffuser (optional accessory) Increases beam angle to 150°×170° Essential accessory when fisheye lens is used, or soft light is required. + Guide number will drop to -1.5EV when it is fitted. Snoot (optional accessory) A strobe adaptor which narrows the beam angle to be directed at a target point. Diameter of the opening 25mm. Designed with internal prism which aligns target light`s light axis and strobe`s light axis to the center. Flash prism (optional accessory) Optical guiding device to fire the strobe when a fiber-optic cable is not used. This device is for manual use only. The device is effective if multiple strobes are used in a fixed position.  However, the flash may not fire depending on the position of where multiple flashes are occurring in relation to that of the master flash.  Excellent visibility Backlight panel that is effective when shooting in dark environments The indicator color on the back of the YS-D3 changes each time the position of the mode switch is changed. Blue (in DS-TTLII mode), light blue (in slave TTL mode), orange (in manual mode with pre-flash), and green (in manual mode without pre-flash) The positioning of the operation system is obvious during night diving. * The color in DS-TTLII mode has been changed from the YS-D2 to match the color with the optical converter. In DS-TTLII mode In manual pre-flash mode   In manual non pre-flash mode Connection method with arm that can be selected according to preference YS-D3 comes with a straight type ball base. Optional YS base and new Diagonal ball base can be installed depending on the application. YS base (common to YS-D1 / D2 / D3) Traditional YS base. Easy vertical swing. Diagonal ball base (only for YS-D3) A ball base inclined at 35 ° compared to the straight type. This makes it easier to lower the strobe backwards, making it suitable for shooting when using a dome port. Also, when a Synchro Cord N is installed, interference between the cord and the ball clamp is minimized.

Light source This is a high-performance strobe that pursues quality of light, and its high luminous flux and wide beam angle are effective for wide-angle photography with fish-eye lenses and other wide-angle lenses. The strobe also features our proprietary light distribution technology. High light intensity GN33 The light output has a guide number (GN) of 33, one of the highest among general-purpose underwater strobes. The use of two discharge tubes increases power and achieves GN 33 at full flashing. Two discharge tubes Uniform and even light distribution The originally developed "aspherical toroidal lens" is placed in front of the light-emitting tube, and the two discharge tubes and the "aspherical toroidal lens" provide uniform and even light distribution to the periphery, making it an ideal light source for external Illumination. Aspherical optical troidal lens Adjust beam angle with diffuser The beam angle is 80°×105° without the diffuser and 100°×110° with the included diffuser for soft lighting. When the optional dome diffuser is attached, the beam angle increases to 150°×170°. The dome diffuser is effective when using a fisheye lens or when lighting with soft light (guide number is reduced by approximately -1.5 EV). Without diffuser With attached diffuser (optional) Dome diffuser installed Operability Sea&Seas particular emphasis on ease of use, especially underwater handling. The more you use it, the more you will appreciate its easy-to-turn dial, easy-to-see panel display, and good underwater balance.

Operates on 4 Readily Avaiable, Inexpensive AA Batteries Various Dome Filters The S-220 strobe is equipped with a bayonet mount to use various dome filters.Packaged dome filters are "Strobe Dome Filter S [SOFT]" which increases strobe beam angle to horizontal 150° x vertical 110° while reducing light intensity by -0.5EV. and "Strobe Dome Filter [ND]" which reduces light intensity by -4EV. specifically for macro imaging.In addition, two optional strobe color filters are available: Strobe Dome Filter S [4900K] and Strobe Dome Filter S [4600K], which warms native strobe color temperature 5500K to either 4900K or 4600K.

The INON Z-330 provides powerful Guide Number 33, high performance and multifunction in its compact body. Its built-in optically designed dome lens offering both high power and wide 110 degree coverage underwater without any diffuser which can sacrifice power. For digital cameras, film cameras, optical connection and sync cable connection, the Z-330 strobe supports every camera system with unparalleled features. Dome Lens Provides Both Powerful Light and Underwater 110 degree Coverage Yet lightweight and compact body, the Z-330 is designed to produce powerful G.N. 33 (*1). Precisely designed front dome lens (*2) together with INON's unique patented "T-shape Twin Flash" successfully manages both powerful strobe light without sacrifice any power and circular 110 degree coverage UNDERWATER. 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 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 Z-330 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 Z-330 can deliver full dump even at 1/1000 high shutter speed setting without cutting power (*1) Measurement in air/ ISO100·m, Nominal value (*2) PAT.

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, 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. Conspicuous Phosphorescence Back Panel - 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. 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 Z-330 strobe 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 from strobe usage effectively. Improved heat tolerance has resolved heat problem typically accompanied with powerful strobe. No stress with sudden stop of flashing to cool down. Minimum Recycle Time "approx. 1.6 sec." at Full Flash Minimum recycle time at full flash (how fast the strobe ready lamp shines and the strobe is ready after making full flash) is approx. 1.6 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 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 Optical connection system widely supports from underwater housings for compact digital cameras to a digital SLR housings with built-in flash or SLRs housing with built-in LED trigger circuitry regardless of make or model. The strobe is equipped with Nikonos 5 pin type cable compatible sync connector to shoot in TTL Auto mode with a film camera or in Manual mode for a digital SLR housing with a bulk head (*4). (*4) Usable function may vary depending on camera system and connection method On-board Wireless TTL The high sensitive slave sensor enables wireless S-TTL Auto mode using a mirror instead of an optical cable. Attaching optional Wireless Connection Kit on the Z-330 and combined with an underwater housing via Shoe Base Set or Grip Base D4 Set creates a handy S-TTL Auto shooting set. * Not 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 Z-330 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.
