Wet Wide Lens 1B (WWL-1B)130 deg. FOV with compatible 28mm lenses (incl. float collar)

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.

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, WWL-1B and previous Nauticam optical designs prove the effort is well spent.

Zoom to Frame

WWL-B is a full zoom through lens, performing well through the entire zoom range of popular compacts, Micro Four Thirds systems with power zoom lenses, and the latest full frame Sony 28-60mm f/4-5.6. 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-1B 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 & Contrast

The cutting edge optical design employed in WWL-1B 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-1B and mounting a macro converter (such as CMC-1 or CMC-2), but in situations where that is difficult close-up shots can still be obtained without removing the wide angle conversion lens.


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 f/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 61 megapixel sensor in Sony A7R IV. 

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.

The WWL-1 and WWL-1B share the same compatibility and you can find complete compatibility details here.  Please note 83250 or 83251 Bayonet Mount Converter II must be used for attaching the WWL-1B.  

Bayonet Mount II

The WWL-1B features the Bayonet Mount II mounting system to maximize ease of use.  Lenses snap into place, and are securely locked. A blue locking tab releases the lens for removal, and lens holders provide storage for lenses on a strobe arm when not in use.  WWL-1B is compatible with PN 83250 M67 to Bayonet Mount Converter II and 83251 M77 to Bayonet Mount Converter II (sold separately).

The bayonet mount system has been designed to incorporate vents that quickly flood the space between lens and camera, washing away air bubbles.

    April/May 2022 Delays:

    Due to further Omicron outbreaks in Hong Kong, some products may be delayed. Not all brands or products will be affected by this. As some products are kept in stock as a matter of course, these should be fine.

    • Brands affected: Nauticam and Bigblue.

    If you need things urgently please contact us and check ETA on the items you require.

    How long will it take for my order to arrive after I make payment?

    That depends on where you live and whether we have an item in stock or not. While we do have many items in stock, we don't carry everything. If you need an item in a hurry, it's a good idea to contact us and find out if your item is in stock.

    If we have it in stock, we can usually send it out as soon as we receive payment, or you can pick it up. If an item is not in stock, we'll need to order it from our suppliers, which means it can take 1-2 weeks to arrive at your door (usually closer to a week).

    Sometimes delivery can take longer, if our manufacturers are out of stock, for example, but this is unusual - we let customers know as soon as possible if something like this happens.

    How do you ship my orders?

    We use New Zealand Post and CourierPost to ship orders. Our default is courier, though you may organise an alternative with us by contacting us directly. CourierPost aims for next day delivery nationwide between major towns and cities in the North Island. South Island delivery can take two days. If you require next-day delivery in South Island, choose the express shipping option for the South Island. If you spend over $250 get your shipping for free!

    When you buy something from us, the price is literally exactly what it says on the tin.

    If you buy something from an overseas supplier, that is most definitely not the case. While the product might seem like a great deal on screen, it's important to understand customs and import costs.

    In addition to the ticket price on an overseas purchase, whatever the exchange rate is on the day (this can fluctuate wildly - trust us, we know), there are also tariffs, GST and border processing fees. This can easily add upwards of 25% to the ticket price. Items costing over NZ$1000 also incur import entry transaction fees.

    In addition to these extra costs, Customs clearance can also cause delays. Sea Tech has been importing for years - we've got this down to a fine art, and we've built relationships with customs that help our items clear quickly.

    By buying from Sea Tech, you avoid all the headaches, delays and extra costs. We handle all this stuff for you, so you don't even have to think about it.
