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.
