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. FOV WITH COMPATIBLE 28MM LENSES (INCL. FLOAT COLLAR) 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-1B and previous Nauticam optical designs prove the effort is well spent. Uncompromised Optical Quality WWL-1B 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-1B 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-1B. 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-1B 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-1B 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.

One of the few wide-angle lenses for smartphones that doesn't distort your images. 

The Dome Lens Extension IIIG uses a multi-coated optical glass lens that provides high image quality under all shooting conditions. Dome lens extensions features a multi-coated optical dome element that effectively suppresses flare/ghost images and provides a sharp image with stable contrast even when shooting in bright and clear water. Installing this super wide-angle option on the UWL-95 C24 increases the underwater angle of view to approximately 141° and reduces the focusing range at a minimum focusing distance of 0 cm to bring the subject into focus on the lens surface. Verdict: Superior ultra-wide dome lens suitable for a wide range of shooting conditions, not only for wide seascapes but also for Close Focus Wide Angle (CFWA). The dome lens extensions IIIA and IIIG use the same lens tube, so that other dome material can be used if necessary (e.g. when replacing damaged original dome material). NOTE: The IIIA/G dome lens unit must be used with the UWL-95 C24 series underwater lens and cannot be used as a standalone lens.

Extend the viewing angle of your smartphone to a whopping 105 degrees in the water. You'll also be able to capture the really big motifs!

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.

(*2) The usable zoom range is between 60 mm and 100 mm (35 mm film equivalent). Outside this range, there is vignetting at wide angle and poorer image quality at telephoto. High magnification with a focal length of 90 mm (+11 diopters). The maximum magnification when using this lens with a 100 mm macro lens for a full-frame SLR system is x2.23 (area ratio x4.98) (*3), which is an intermediate performance between "UCL-67" (+15 diopters) and "UCL-165" (+6 diopters). The UCL-67 offers high magnification and a long working distance at the same time. When used with a 100 mm macro lens for SLR cameras, the working distance is 69 mm at minimum focal length (*3). Together with its compact size, the lens provides friendly illumination even at minimum focusing distance. (*3) When used with the AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED. Designed exclusively for underwater use, the lens effectively suppresses aberrations throughout the focal range to deliver sharp, high-contrast images even at close shooting distances. (*4). (*4) This lens is designed for underwater use only. When used on land, the subject will not be enlarged and distortion will occur at the edges of the image or vignetting, etc. The use of HR glass makes the lens compact and suitable for a wide range of camera systems, from 100mm macro SLR lenses to compact digital cameras (*5). The compact lens body also means there are fewer lighting restrictions, so you can use a variety of lighting techniques. (*5) The usable zoom range is between 60 mm and 100 mm (35 mm film equivalent). Beyond this range, there is vignetting in the wide-angle range and poorer image quality in the telephoto range. The lens consists of 3 elements in 2 groups and effectively suppresses chromatic aberration by using an achromatic lens inside. An anti-reflective coating on all lens surfaces also suppresses flare/glare. The optional "Lens Adapter Ring for UCL-67" attaches to the M65 thread of the UCL-67 and allows the INON M67 series "UCL-165M67"/"UCL-330" to be stacked on the front of the UCL-67 for even higher magnification for super macro photography. (*6) (*6) Other close-up lenses with higher magnification, such as "UCL-67 M67","UCL-90 M67" or "UCL-100M67", are not recommended due to deterioration of image quality. The lens mount is the versatile "XD Mount" bayonet mount.

Ultra Wide Even Underwater Though an action camera is equipped with ultra wide lens, its coverage underwater will dramatically narrow down due to different refraction ratio between air and water. For example, maximum angle of view of GoPro® HERO10 Black is approx. 151° on land which will narrow down to approx. 94° when we put the camera in genuine dive housing and bring it underwater due to different refraction index. The INON UFL-G140 SD provides ultra wide semi-fisheye imaging with angle of view 140° underwater enabling wild underwater video work only with action cameras. * Measured angle of view by INON or calculated angle of view underwater based on the measured angle of view. Not confirmed by camera manufacture. The measured angle of view of “HERO3+ Silver Edition” is approx. 142°(air) which is less wide than the “Black Edition”. So angle of view underwater with this lens is less than 140°. The “HERO3+ White Edition” has not been tested. Dynamic CFWA Imaging Shooting through the INON UFL-G140 SD lens enables you to shoot a subject at close range to benefit deformed and/or perspective result. The native depth of field (DoF) of the GoPro® HERO10 Black on land is approx. 60cm/2ft to 8. With the INON UFL-G140 SD, DoF underwater will be extended to 4cm/1.6in to 8 closer to camera side. * DoF on land is based on focal length/aperture of camera lens and pixel pitch of the image sensor. DoF underwater is measured from "the forefront of the lens".

Diese Fisheye-Vorsatzlinse ist eine so genannte "Insektenaugenlinse". Das Objektiv ist so konstruiert, dass es bei ca. 80 mm Zoomposition (35 mm Film-Äquivalent) genutzt werden kann, anders als Standard-Weitwinkelkonverter (*4). Der Blickwinkel beträgt 150°. Das objektseitige Objektiv hat einen kompakten Durchmesser von 32,9 mm und einen minimale Fokussierabstand von 0 cm, um ein winziges Objekt im gesamten Bild zusammen mit dem Hintergrund zu erfassen. Das UFL-M150 ZM80 ist ein Objektiv zur Konvertierung des afokalen Systems, das die Lichtstärke des kombinierten Masterobjektivs nicht beeinträchtigt und Ihnen die Nutzung der Vorteile des AF (Autofokus) der Kamera ermöglicht. Sie können die Vorteile der INON "S-TTL" Belichtungsautomatik der INON Z-330, D-200, S-2000 voll ausnutzen, um durch einfaches Drücken des Auslösers geeignete Belichtungsbilder zu erhalten. Der Objektivtubus hat eine Gewindewand, um die Linsenposition vor und zurück zu justieren, um mit verschiedenen Masterobjektiven unter vielen kompakten Digitalkameras (*5) übereinzustimmen. Die UFL-M150 ZM80 wird auf einem kompatiblen Kameragehäuse mittels einer Kombination aus "Mount Base", die exklusiv für jedes Gehäuse entwickelt wurde, und einem geeigneten "Mount Converter" befestigt.  (*1) Der optionale "M27-M67-Mount Konverter für UFL-M150 ZM80" ist erforderlich.(*2) Der optionale "M27-AD Mount Converter für UFL-M150 ZM80" ist erforderlich.(*3) Der optionale "M27-LD-Mount-Konverter für UFL-M150 ZM80" ist erforderlich.(*4) Dieses Objektiv ist nur für den Unterwassereinsatz vorgesehen. Bei Verwendung an Land wird kein Bild erzeugt.(*5) Nicht verwendbar für eine kompakte Digitalkamera mit großem Master-Objektiv oder Super-Zoom-Funktion oder ein Wechselobjektiv für ein SLR-Kamerasystem.
