TTL-Converter for Sony A6xxx for SEAFROGS (MEIKON) housing

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.  

Developed by underwater photographers for underwater photographers - with this claim Retra UWT has dedicated itself to the development of one of the best underwater flash units in the world.  Focus on light quality With a unique flash tube design and a completely new reflector, Retra-UWT has achieved a light output that no other flash unit of this size can offer. But it is not only about guide numbers. "All you need to remember about guide numbers is not to use them as a guide when buying a flash. The guide number is determined by both the light output and the spread of the beam. A focused beam produces a much higher guide number than a widely scattered beam, but the latter is more desirable underwater." Alex Mustard in the Underwater Photography Masterclass (2016) The user interface created by photographers By listening to underwater photographers using the original Retra Flash, the developers have optimized the user interface. The interaction and functionality of the new Retra Flash is even more intuitive and precise. Double O-ring and leak detector for the battery compartment Our goal is to achieve a 0% statistic for battery compartment flooding. Therefore we introduce a double O-ring on the battery cover and on the optional leak detector. In the unlikely event that the battery compartment is flooded, you will be notified by the Retra Flash to check the battery compartment as soon as possible.  Performance in numbers Flash power: 150 Ws Colour temperature: 4900 K Pilot light output (angle): 500 lm (20º) Recycling time at 100% power (4x Eneloop pro): ~3 s HSS ready: YES Power levels: 13 Leak detector: YES Bayonet connection type: A1 Electrical connection: via converter Optical connection (compatible with Inon and Sea&Sea connectors): YES Weight (without batteries, including 1" mounting ball): 790 g 

THE SONY A6600 E-MOUNT APS-C CAMERA The Sony a6600 is the new flagship model of the venerable APS-C mirrorless line. The a6000 series benefits from a large lens selection and bright Electronic Viewfinder paired with a large 24.2MP Exmor CMOS sensor and high-powered latest generation BIONZ X processor in a compact travel-friendly package. For the a6600 Sony is adding a host of features that will benefit the underwater image maker whether shooting video or stills. Key Camera Specs 24.2 APS-C Exmor CMOS Sensor ISO Range of 100-32000 810 shot (CIPA standard) Battery 4K 30p HLG 100Mbps Video Recording Unlimited video record time IMPROVED PROCESSING Sony's 4D autofocus system provides ultra-fast 0.02s and accurate tracking autofocus, taking advantage of the camera's 425 phase-detection autofocus points. With 11fps continuous shooting the a6600 will insure sharp images of fast action scenes. With the new BIONZ X processor comes improved low-light performance and an expanded base ISO range of 100-32,000. With the a6600, when using Auto ISO mode, minimum and maximum ISO values can now be set. 4K VIDEO PERFORMANCE Combined with 5-axis optical image stabilization and HLG 4K 30p video recording, the A6600 is sure to be a video shooter favorite. The 4K footage from the a6500 is oversampled, using the full sensor-width at 24p and downsampling the final result which leads to increased sharpness. For 4K at 30p, the a6600 uses a 1.23x crop. When shooting high-speed FHD at 120p or 100p the footage is from a 1.14x crop. Sony also removed the 30-minute recording time limit restriction. Using the HLG Picture profile for video capture preserves the maximum dynamic range available, allowing for more latitude in post production. ENHANCED CUSTOMIZATION The a6600 has gained a well-placed 'C3' custom button in addition to the existing 'C1' and 'C2' which are located on the top of the housing. The new 'C3" is located on the rear of the housing within thumb's reach. The a6600, similar to its predecessors is greatly customizable to fit the shooter's needs. THE NAUTICAM NA-A6600 UNDERWATER HOUSING Nauticam is the industry leader in mirrorless interchangeable lens underwater camera support. Nauticam has housed more mirrorless cameras, and more Sony E (NEX) Mount cameras than any other housing manufacturer. This experience results in the most evolved housing line with broadest range of accessories available today. Pioneering optical accessories elevate performance to a new level. Magnifying viewfinders, the sharpest super macro accessory lenses ever made, and now the highest quality wet mount wide angle lens (the WWL-1) combine with the NA-A6600 housing to form a complete imaging system. Nauticam is known for ergonomics, and an unmatched experience. Key controls are placed at the photographer’s fingertips. The housing and accessories are light weight, and easy to assemble. The camera drops in without any control presetting, and lens port changes are effortless. NA-A6600 features an integrated handle system. This ergonomic style provides exceptional control access, even with thick gloves, with ideal placement of the shutter release and a thumb-lever to actuate the AE-L / AF-L button from the right handle in addition to the new 'C3' customizable button. Nauticam build quality is well known by underwater photographers around the globe. The housing is machined from a solid block of aluminum, then hard anodized making it impervious to salt water corrosion. Marine grade stainless and plastic parts complete the housing, and it is backed by a two year warranty against manufacturing defects. NOTE: The NA-A6600 is NOT compatible with (36206) N85 to N120 50mm Adapter. It requires the updated (36207) N85 to N120 50mm Port Adapter II. HDMI 1.4 OUTPUT With 4K HDR internal video recording and updated autofocus, pairing the NA-A6600 with an external monitor such as the SmallHD 502 Bright 5" gives video shooters a large, bright screen that features focus and exposure tools. HDMI 1.4 output requires HDMI Bulkhead (25032) as well as a supported monitor housing and internal HDMI cable (25076). WWL-1, CMC-1, AND CMC-2 Three in-house Nauticam optical designs, designed by founder and Managing Director Edward Lai, are the perfect lenses to complete an a6600 underwater system. The magic of the wet lenses is their tremendous versatility, paired with outstanding in-water performance. Both macro and super wide angle optics are available to the underwater photographer on the same dive. These lenses are completely engineered for use in water, providing the highest image quality available today in a wet mount optic. WWL-1 is a wide angle conversion lens, compatible with several lenses in the Sony system. The field of view is widest when paired with the Sigma 19mm f2.8 DN Lens, providing 130 degree diagonal field of view. WWL-1 is also an ideal match for the Sony E 16-50mm F3.5-5.6 PZ OSS lens providing over 100 degree diagonal field of view with full zoom through! With either lens on camera, class leading center sharpness, corner sharpness, and contrast result in the clearest wide angle images possible underwater. CMC-1 and CMC-2 provide the best macro performance available, with two different magnification strengths, suitable for a wide variety of macro subjects. With the popular Sony E 16-50mm F3.5-5.6 PZ OSS lens, CMC-1 is capable of capturing a macro frame 26mm wide, while CMC-2 captures an area 33mm wide. CMC-2 is less strong, making it easier to use with more accurate autofocus. CMC-1 is best suited for the smallest of macro subjects. Macro enthusiasts will surely want both! FAST AND RELIABLE FLASH TRIGGERING Reliable rapid fire manual flash triggering is available with the NA-A6600 for a variety of optically fired flashes when used with a new LED Flash Trigger (36315). The NA-A6600 comes fiber optic ready and accepts standard Sea & Sea style bushing connections. Strobes and light arms can be attached to the housing via included 1? accessory mounting balls. The housing also features a cold-shoe and M10 threaded mount for a focus light or other accessories. Electrical strobe triggering (with power set manually on the flash head) is still an option for those with an investment in legacy lighting gear, requiring the purchase of an accessory electrical bulkhead. BATTERY PACK FOR NA-6600 HOUSING (2500MAH, INC. USB CABLE) (NA36332) The a6600 does feature a larger internal battery but especially when shooting video the benefit of an accessory battery pack greatly extends the time between battery swaps, and allows the housing to remain sealed between dives. The accessory battery pack rests securely below the camera inside the housing and provides power to the camera via USB. INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM The Nauticam vacuum check and leak detection system is available with NA-A6600 as standard equipment. Combined with an optional vacuum valve (PN 25624), this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur.
