M67 to Bayonet Mount Converter II

Replacement plastic cap for the M67 to bayonet adapter (II) by Nauticam

In order to use the CMC/SMC with the Bayonet Mount System this adapter is required. It threads onto the CMC or SMC.

This focus unit is part of Nauticam's eMWL. This unit is used by the macro lens to capture the virtual image of the lens and relay unit accurately and sharply. It cannot be used alone. The focus unit is attached to a suitable housing port with a bayonet connection (alternatively with the M67 to bayonet adapter II NA83250). The relay or lens unit is also attached with a bayonet Connection.

The next evolution of the WWL-1 is here!   As the versatility and capability of compact cameras increases, Nauticam has developed a smaller and lighter water contact wide angle lens tailored specifically to the compact camera user.  Designed from the ground up to match the compact camera's form factor without sacrificing optical quality, the WWL-C is a powerful addition to not only Nauticam compact housings but also, via an optional adapter, to those from other manufacturers such as the Olympus TG-6 and their PT-059 housing. Introducing Wet Wide Lens for Compact Cameras (WWL-C) With the original Wet Wide Lens, the WWL-1, Nauticam used computer aided lens design software to create an underwater-specific corrective lens that allowed for an unprecedented 130º field-of-view with full zoom-through optics and extreme close focus capabilities.  The WWL-1 wasn't just for higher end cameras that already benefitted from interchangeable lenses to attain better image quality, the WWL-1 was designed to work with a variety of cameras that featured a 28mm equivalent lens including compacts and micro-four thirds.  Delivering a stunningly sharp 130º field-of-view with 24mm equivalent lenses, the WWL-C also features zoom-through capable optics.** The WWL-C features a pre-installed metal buoyancy collar and a non-removable metal dome shade.   The WWL-C will also feature an updated quick-release Bayonet Mount.  Lenses that feature the new Bayonet Mount II will not be compatible with previous Bayonet Mount adapters but all Bayonet Mount lenses will be able to be used with the new Bayonet Mount II Bayonet Mount Adapters without modification.   In the sidebar you will find a list of anticipated housing compatibility along with the supported focal-length range as well as the necessary port configuration for the Bayonet Mount II standard. Compact Housings The WWL-C is designed around the 24mm focal length which is commonly the widest focal length for fixed-lens compact cameras.  While the WWL-1 was also able to deliver 130º field-of-view it required that the camera's lens be zoomed in slightly to 28mm.  With the WWL-C, there's no more need to zoom to avoid vignette!  This also means that more of the camera's zoom range is available.   The new NA-TG6 (17816) for the Olympus Tough TG-5 and TG-6 cameras is WWL-C ready out-of-the-box as it comes with the new Bayonet Mount II converter pre-installed.  With the TG-5 and TG-6 the WWL-C allows for use of the 25-100mm zoom range! For those compact housings with the N50 interchangeable port system, there are new short ports with Bayonet Mount II adapters pre-installed. Configurations for some of the latest models: Sony RX100 VII in the NA-RX100VII use (38705) N50 Short Port 17 with Bayonet Mount with a usable zoom range of 24-30mm Canon PowerShot G5X Mark II in the NA-G5XII use (38703) N50 Short Port 25 with Bayonet Mount with a usable zoom range of 24-50mm Panasonic Lumix DMC-LX100 II in the NA-LX100II use (38704) N50 Short Port 22 with Bayonet Mount with a usable zoom range of 24-30mm Complete configurations for all supported models can be found on the Port Chart for the WWL-C. Mirrorless M4/3 Housings The WWL-C is not just for compact cameras!  The Panasonic LUMIX G VARIO 12-32mm F3.5-5.6 ASPH. MEGA O.I.S. lens, when used with (36165) N85 Power zoom macro port 29 and the (83250) M67 to bayonet converter II allows for the use of the full 12-32mm zoom range. Mirrorless APS-C Housings Sony, Canon, Nikon and Fuji Mirrorless APS-C can all benefit from the WWL-C.  The Sony SELP1650 E PZ 16-50mm F3.5-5.6 OSS offers excellent performance from 17-50mm with only slight vignetting at 16mm.  The compact size of the WWL-C works in tandem with the low profile series of Nauticam housing for Sony's E-mount APS-C series of cameras such as the NA-A6600 and NA-A6400 to provide a travel-friendly package that doesn't compromise optical quality. Adapter for Olympus PT058/PT059 Housings Using the WWL-C with the Olympus PT058 and PT059 Housings for their Tough TG-5 and TG-6 cameras is now also an option with the (83256) Bayonet Mount Converter for Olympus PT058/059.

Footage by Uli Kunz with Sony A7SIII and SEL90M28G in Nauticam-Housing with eMWL  The eMWL as a modular system The eMWL was developed as a modular design with three individual parts: the focusing unit, the relay module and the lens. Nauticam has developed components optimized to work with different camera manufacturers and their macro lenses, as well as a selection for three unique perspectives. Let's take a look at each part and dive a little deeper into the eMWL. The complete eMWL system Objective lenses, 60°, 100°, 130° - Relay unit - Focusing unit eMWL-Focusing unit Three focusing units have been developed to ensure the best results on a range of cameras, and each unit is optically matched to the recommended prime lenses. The eMWL is very sharp and has very good contrast, and the autofocus works very well.  This is a significant advantage over other relay lenses available. You also have the option to add a manual focus gear. You can also use lens adapters like the Nikon FTZ, EF to EOS R or the Sigma MC-21. The focusing unit is the part closest to your port, it is designed with 6 glass elements in 3 groups and is connected via the bayonet lock system.  Focusing unit (NA87203) for Sony Compatible lens: Sony SEL90M28G FE 90mm F2,8 Makro G OSS  eMWL-Relay unit The next element to be attached to the front of the focusing unit is the relay lens. It was designed to the highest standard with 14 glass elements in 10 groups. The eMWL objective lenses create an inverted image so that it appears upside down. The relay lens corrects the inverted image and returns the image to the focusing unit and sensor. It is 150 mm long and only 62 mm wide at its widest point. This allows the front of the eMWL to be placed extremely close to your subject while keeping the bulk of the camera system and the photographer at a greater distance. It also opens up creative possibilities for videographers to capture motion shots in tight spaces. Imagine poking through sea grass to expose a young batfish, or pulling back from a small subject to show the nook where it lives. All three focusing units use the same relay lens. It is possible to use the eMWL without the relay lens if you do not need the extended working distance. But then a camera or monitor that can correct the inverted image in the electronic viewfinder or screen is advantageous. eMWL-Objective Lenses The final piece that attaches to the front of the Relay Lens is the Objective Lens. There are three different versions with varying degrees of angle-of-view. You would choose one based on the look, subject or type of image you would like to produce. These, like the other two parts, can all be put together and disassembled underwater. You could keep all three objective lenses with you and swap out when needed. You can shoot these just like you would any other lens, but the real magic happens when you get up close to your subject. The 130° and 100° objective lenses will focus as close as the front element and the 60° objective lens can focus as close as 15mm. You could fill up most of the frame with a nudibranch and still have room for a diver in the background! The EMWL is a great tool to boost your creativity. 130° Objektive Lens (NA87223) This is the widest of the three Objective Lenses, designed with 9 elements in 7 groups. It is perfect for larger macro subjects or any image where you want to see more of the background. The image quality rivals the best wide angle lenses so feel free to shoot it for traditional wide angle shots as well.  100°-Objective Lens (NA87222) This is an extremely versatile angle of view. It is the smallest and sleekest in physical size making it a good choice for timid subjects and tight spaces. It is designed with 9 elements in 6 groups. An angle of view of 100° is still a lot of background space for small macro subjects or to shoot wide angle with. A 16mm lens on FF is 107° for comparison.  60°-Objective Lens (NA87221)  For a narrower angle-of-view or if you would like the background elements to look more compressed, than the 60° objective lens is the perfect choice. It is designed with 9 elements in 6 groups. There are three focusing ranges that can be set on the lens, 8-55mm, 55-25mm and 25-15mm. I would suggest setting it to the 8-55mm setting and adjust to one of the closer settings when working extremely close to a subject. The closer setting work similar to an extension tube by moving the lens further away from the sensor. Bayonet mount The EMWL uses the Nauticam Bayonet Mounting System. You can easily attach or remove the EMWL to shoot with just the macro lens or add other accessories. You will need to add the appropriate Bayonet Mount Converter to the front of your port. If you wish to use a Super Macro (SMC-1 or SMC-2) or Compact Macro Converter (CMC-1 or CMC-2), they can be attached with an optional Bayonet Mount Adapter.

The WWL-1 is the highest quality wet-changeable underwater wide-angle conversion optic ever made, featuring unmatched contrast, overall sharpness, corner sharpness, and clarity. The design is truly full zoom through, allowing zoom to to be used as a tool for framing, and removable in water for close-up and macro shots. NA-GX7 & Nauticam WWL-1 Lens Showreel from Nauticam on Vimeo. Breakthrough lens design Every Nauticam lens is a "clean slate" design. These optical systems are engineered entirely as underwater corrective and conversion optics, and not adaptations of in air designs. The process isn't an easy one, but the images captured by WWL-1 and previous Nauticam optical designs prove the effort is well spent. Uncompromised Optical Quality WWL-1 is constructed of 6 precisely ground elements of highly refractive optical glass. All internal elements are coated with a broadband anti reflective coating to keep flare and internal reflections to an absolute minimum. WWL-1 besteht aus 6 präzise geschliffenen Elementen aus hochbrechendem optischem Glas. Alle Innenelemente sind mit einer breitbandigen Anti-Reflexionsschicht beschichtet, um Streulicht und Innenreflexionen auf ein absolutes Minimum zu reduzieren.   Zoom to frame WWL-1 is a full zoom through lens, performing well through the entire zoom range of popular compacts and Micro Four Thirds systems with power zoom lenses. This feature distinguishes this lens from all others on the market, which are designed to be used at a single focal length. The ability to be used with zoom makes WWL-1 extremely versatile! A touch of zoom can be used to crop a subject in camera, or for close-up shots without removing the lens. Stunning field of view 130 degrees of glorious wide angle coverage, and even a bit wider if your camera system allows it! This is a field of view that sits between the popular full frame fisheye lenses (180 degrees diagonal) and ultra wide rectilinear zooms (approximately 110 degrees). This coverage angle was targeted from the very beginning as an ideal coverage angle for a wide variety of underwater imaging scenarios. Big animals, close focus wide angle shots of reef dwelling creatures, and even mid-range fish portraits are all within the range of WWL-1. Incredible sharpness and contrast The cutting edge optical design employed in WWL-1 results in extremely high overall sharpness, contrast, and edge sharpness. The design is optimized for the high resolution sensors of today, as well as the even higher resolutions sensors of tomorrow. Close focus The ability to focus close is key, and WWL-1 does amazingly well. With all compatible systems at wide angle the lens is able to focus on the front of its dome lens element, maximizing the impact of even small subjects. Amazingly, with the Panasonic 14-42 Power Zoom, the lens is still able to focus on the front of the dome port when zoomed to full telephoto! The best macro images will always be obtained by removing WWL-1 and mounting a macro converter (such as CMC or SMC), but in situations where that is difficult close-up shots can still be obtained without removing the wide angle conversion lens. Compatibility Wet lenses have traditionally been an accessory geared toward compact cameras, but Nauticam set out from the very beginning to support a wider range of systems, with larger sensor sizes. Most impressive is the outstanding performance available with the full frame Sony A7 series cameras using the Sony 28mm /2 Prime lens. In our tests, this combo out-performed all of the Sony wide angle lenses behind dome ports, and is especially well matched to the demanding 42 megapixel sensor in Sony A7R II. Micro four thirds systems used with power zoom lenses are another compelling combination. 130 Degrees on the wide end, with a 3x Zoom Range, and close focus on the front of the dome. This combination is wider, sharper, and has less distortion than the Panasonic 7-14 F/4 and Olympus 7-14 F/2.8 lenses behind a dome port. Twist off the lens, and snap on a CMC for high powered macro photography, capturing an image area 22mm (just under 1″) wide! The full range of compatible systems is listed below. Simple bayonet mounting A new bayonet mounting system has been designed to accompany the WWL-1 release, and maximize ease of use. Lenses snap into place, and are securely locked. A red locking tab releases the lens for removal, and lens holders provide storage for lenses on a strobe arm when not in use. The bayonet mount system has been designed to incorporate vents that quickly flood the space between lens and camera, washing away air bubbles. Both 67mm and Bayonet mounting rings are included with the lens as standard equipment, and Bayonet Mount Converters are available separately (providing the attachment point on a housing or port).

The new eMWL (Extended Macro Wide Lens) from Nauticam is built to work with multiple common macro lenses and is optimised for both still images and video. It is a wet lens design, so the lens can be attached and removed underwater. This adds to the versatility of the whole system, and other accessories such as SMC and CMC macro converters can also be used. The eMWL as a modular system The eMWL has been developed as a modular design with three individual parts: the focusing unit, the relay module and the lens. Nauticam has developed components optimised to work with different camera manufacturers and their macro lenses, as well as a selection for three unique perspectives.

There are three different versions with different angles of view. You choose one of the three depending on the look, the subject or the type of image you want to create. These, as well as the other lenses, are available in three different versions. These, as well as the other two parts, can all be assembled and disassembled underwater. You can keep all three lenses with you and replace them if necessary. You can shoot them just like any other lens, but the real magic happens when you get up close to your subject. All three lenses focus as close as the front element with the right setting. You could fill the largest part of the frame with a nudibranch and still have room for a diver in the background!

It is the smallest and slimmest in its physical size, making it a good choice for narrow subjects and tight spaces. It is designed with 9 elements in 6 groups. An angle of view of 100° is still plenty of background space for small macro subjects or for wide angle shots. For comparison, a 16mm lens on FF is 107°.  60°-Objektiv (NA87221) For a narrower angle of view or when you want the background elements to look more compressed, the 60°lens is the perfect choice. It is designed with 9 elements in 6 groups. There are three focusing ranges that can be set on the lens: 00-55 mm, 55-25 mm and 25-0 mm. I would suggest setting it to the 00-55mm setting and adjusting to one of the closer settings when working extremely close to a subject. The close-up setting works äsimilar to a tube by moving the lens further away from the sensor. Bayonet connection The EMWL uses the Nauticam bayonet mounting system. You can easily attach or remove the EMWL to shoot with just the macro lens or add other accessories. You will need to attach the appropriate bayonet converter to the front of your port. If you need to use a super macro (SMC-1 or SMC-2) or compact macro converter (CMC-1 or CMC-2), they can be attached with an optional bayonet adapter.

This focus unit is part of Nauticam's eMWL. This unit is used for the macro lens to capture the virtual image of the lens and relay unit accurately and sharply. It cannot be used alone. The focus unit is attached to a suitable housing port with a bayonet connection (alternatively with the M67 to bayonet adapter II NA83250). The relay or lens unit is also attached with a bayonet connection.

The next generation of WWL-1 is here!  The WWL-1B features the same stunningly sharp optics as the WWL-1, but it now includes an integrated aluminum buoyancy collar to make it nearly neutral in water.  The WWL-1 and now WWL-1B are still the highest quality wet-changeable underwater wide-angle conversion optics ever made, featuring unmatched contrast, overall sharpness, corner sharpness, and clarity. The design is truly full zoom through, allowing zoom to to be used as a tool for framing, and removable in water for close-up and macro shots. INTRODUCING WET WIDE LENS 1B (WWL-1B) 130 DEG.
