An underwater flash designed for macro The Backscatter Mini Flash 2 MF-2 is a major upgrade to the Backscatter Mini Flash MF-1, with tons of new features and performance upgrades, including Olympus TTL, remote strobe control, high-speed sync, test mode, emergency signaling capability, a faster recycle time, and LED lights that are twice as bright as the previous model. All of the accessories from the Backscatter Mini Flash MF-1 carry over to the Backscatter Mini Flash 2 NEW: Automatic TTL For Olympus Cameras NEW: Wireless Remote Control NEW: High-Speed Sync NEW: Built-In 1000 Lumen Focus Light NEW: Test Mode & Beacon NEW: Faster Recycle Time NEW: Bigger Battery, Longer Run Time Most of the conventional wisdom surrounding underwater strobes is that brighter and wider always equals better. If you're shooting macro underwater photography, you want the exact opposite. You want a tightly controlled light to pinpoint the subject and keep the background as dark as possible. The Mini Flash 2 is the perfect flash + snoot combination for any serious underwater macro photographer. Its tiny size can get into the tightest spots and the companion Optical Snoot OS-1 makes it the perfect macro strobe to give you the creativity you've been missing. WIRELESS REMOTE CONTROL The Backscatter Mini Flash 2 features a remote transmit and receive function for wireless remote control and triggering. The remote system works by the main transmitting strobe having the ability to remotely adjust the power level of other Mini Flash 2 receiving strobes. The included Light Pipe attaches to the fiber optic mount of the Mini Flash 2 and allows for receiving the signal from the transmitting strobe without the need for a fiber optic cable or an electronic trigger. No cables and no reaching out for a remote strobe to change power levels means less silt from moving around or potentially freaking out the critter you’re trying to take a picture of. This works great for off-camera remote side lighting, backlighting, and snooting from the new Backscatter Remote Lighting Muck Stick. Remote lighting is now easy to deploy and a breeze to use. Remote lighting can create a whole new look for subjects that normally blend into their environment. The first shot above is with just the Mini Flash 2. The second shot is with a remotely placed Mini Flash 2 and Optical Snoot OS-1 on the Remote Lighting Muck Stick placed above and behind the subject. The third shot is with the Mini Flash 2 and Optical Snoot OS-1 lighting the front and a remotely placed Mini Flash 2 and Optical Snoot OS-1 with the Backscatter Color Filter System on the Remote Lighting Muck Stick placed above and behind the subject. 1000 LUMEN BUILT-IN FOCUS LIGHT With powerful 1000-lumen LED focus lights built-in, there’s no need for a separate focus light to manage on your rig. It makes a perfect companion for compact camera shooters looking for a great all-around streamlined strobe solution. It’s also the perfect solution for advanced mirrorless and SLR shooters looking to reduce their footprint, simplify their lighting and lighten their rig for easier shooting. The LED lights in the Backscatter Mini Flash 2 are now twice as bright as the previous Backscatter Mini Flash MF-1 making this the absolute easiest strobe and snoot combination to use. Even in bright shallow conditions, it is super easy to see the target light from the snoot in the same exact shape and position as the flash. With no guessing on where the flash will fire, the Mini Flash 2 makes it as easy as can be to get perfect snooted shots right out of the box. The LED lights will run up to 90 minutes on a full 21700 battery. AUTOMATIC TTL FOR OLYMPUS CAMERAS The Backscatter Mini Flash 2 is compatible with Olympus’s TTL protocol through RC mode. In our testing, the Olympus RC system produces the most consistent and accurate TTL exposures of any underwater system. The Mini Flash 2 takes this a step further by also having an option for finely tuned macro TTL. Most TTL systems from camera manufacturers have not been optimized for close-up macro use. This usually results in TTL not working well at close distances and lower flash outputs associated with macro, leading to overexposed images. The Mini Flash 2 has a TTL mode specifically tailored to macro that allows for better and more accurate exposures when compared to other systems available. Exposure compensation is possible in TTL and is controlled directly from the camera, but most likely won’t be needed. TTL even works through the Optical Snoot OS-1 for perfect snooted exposures! HIGH SPEED SYNC High Speed Sync (HSS) is where the camera can shoot faster shutter speeds than the camera’s flash sync speed by using a special mode on the underwater flash. HSS allows for wider open apertures while still being able to maintain a darker background than otherwise would be possible at slower shutter speeds. Olympus mirrorless cameras can achieve HSS through Olympus RC mode with compatible housings such as the Backscatter Octo Housing for the Olympus Pen camera or with other brand mirrorless and SLR cameras including Sony, Nikon, and Canon with 3rd party flash triggers that support HSS such as UW Technics and the Turtle trigger from TRT Electronics.

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. Large dial Underwater operation is performed with the mode switch and light intensity control dial. The large dials are non-slip and the height difference allows smooth operation even when wearing thick gloves. It is designed to stop in steps with a click-click to minimize malfunctions. Large dial Easy-to-read backlit panel The indicator color changes each time the mode switch is repositioned. Blue (in DS-TTLII mode), red (in RC mode), yellow (in manual mode with pre-flash), and green (in manual mode without pre-flash) are the different colors for identification, so positioning of the controls is easy to see even when night diving. In DS-TTLII mode In RC mode In manual non pre-flash mode Underwater Balance YS-D3 DUO by Sea&Sea has almost zero buoyancy with the ball mount and clamp in place. Heavy underwater weight requires unexpected force to operate the clamp, but the YS-D3 DUO is unaffected by buoyancy, so operation is smooth. Even if you change the strobe position, the underwater balance of the entire housing set does not change significantly and you can feel how easy it is to handle. Two patterns of target lights The LED target light function is useful for focusing and checking the beam angle of the strobe. Choose either 300 lumens or 150 lumens depending on the situation. 300 lumen 150 lumen One-touch battery replacement The power source is AA batteries, which are widely distributed in general. Four of the same type (1.5V alkaline AA batteries and 1.2V nickel-hydrogen AA batteries). The battery box is opened and closed by a bayonet type that does not put a burden on the O-ring. It is a one-touch operation and does not require force like the screw-in type. Hook for Fiber Optics A hook for fiber-optic cable on the strobe body smartly guides the fiber-optic cable.

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.

The YS-01 underwater flash from Seas&Seas, the best-selling flash unit in its class, has been redesigned and now has improved performance. Same DS-TTL ll control as the high-quality Sea&Sea models The DS-TTL ll control circuit helps to automatically emit the correct amount of light based on the light intensity of the camera's built-in flash. The flash allows you to set the light intensity stronger or weaker than the programmed standard exposure. This feature allows even an inexperienced underwater photographer to instinctively control the amount of light they want. Example: If you are using two YS-01 Solis flash units, one on the right and one on the left, and there are white soft corals on the right of your photographic subject, you can subtly reduce the light intensity of the flash unit on the right alone by simply setting the brightness control to minus. With the improved circuitry, you can achieve the desired lighting for all your underwater shots in no time at all. Increased light intensity from the pilot light Compared to the previous model, the light intensity of the focus light of the YS-01 Solis is 40 percent stronger, which has improved the visibility of the light beam and helps you to judge the position of the flash more accurately.   Superior light distribution and wide beam angle Due to the exclusively developed prismatic lens, the YS-01 Solis realises a wide beam angle of 100°x 100° with an ideal flat light distribution, even when the accessory diffuser is not attached. With the diffuser, the light becomes softer and the beam angle increases to 110°x 110°.

Specifications Suitable for INON Z-330 underwater strobe. Consists of DelRin and 2 mm diameter fibre optic cables. Suitable for Saga and Nauticam macro diopter lenses(SMC-1, CMC-1 & CMC-2) Features The Saga fibre optic ring flash for macro lenses, is an accessory that focuses the light from the flash using fibre optics. Its operation is simple: it attaches to the flash head to direct the light through the fibre and bring it in front of the attachment lens. It is ideal for extreme macro photography at a professional level. The working range is that allowed by the magnifying lens, approximately between : 2.5 and 10cm. By providing a circular light, you can compose the image either horizontally or vertically and you get correct illumination in difficult places that you could not illuminate with a conventional flash (cracks, holes, etc.).

Simple and versatile remote TTL flash Since the YS-03 SOLIS is designed to mimic the light intensity of the camera's built-in flash, it is not necessary to manually adjust the output. The YS-03 SOLIS is compatible with any camera that has a pre-flash and TTL flash exposure function, regardless of make. Simple operation Designed with every underwater photographer in mind, the YS-03 SOLIS is easy to understand and use. The only control is the rotary power switch, and by simply turning the switch from OFF to TTL, you can capture beautiful images. Supplied with diffuser as standard The semi-translucent section diffuses and attenuates the light from the underwater flash. Using the diffuser results in softer, more evenly exposed images. The diffuser also helps to reduce the effects of overexposed images or when strong light creates shadows/shadows in the image. 

Easy and Versatile Slave TTL As the YS-03 SOLIS has been designed to mimic the light intensity of the camera’s built-in flash, it is not necessary to manually adjust output. The YS-03 SOLIS is compatible with any camera with a pre-flash and that has a TTL flash exposure function, regardless of make. Taken without strobe (ambient light) Taken with the YS-03 SOLIS Simple Controls The YS-03 SOLIS has been designed for any underwater photographer to use and is easy to understand. The only control is the rotary power switch and by simply turning the switch from OFF to TTL you can take beautiful images. Charged and ready to trigger. TTL exposure confirmed. Comes with diffuser as standard The half-translucent section diffuses and softens the light from the strobe. Using the diffuser gives softer, more evenly exposed images. The diffuser will also help reduce effects of overexposed images or when strong light produces shade/shadow in the image.

The Weefine WFS02 ring flashes have been specifically designed for underwater use to provide colourful and natural wide-angle illumination . A professional-grade round flash tube and powder-coated reflector perfectly produce a soft, blindingly warm 5500K light. A 200 lumen white pilot light and a 2 watt red light help with night photography and beautiful subjects.

A great value strobe package which includes everything you need to combine the YS-01 SOLIS with most compact camera/housing combo’s.
