Fantasea and AOI Introduce UWL-04F Wet Wide-Angle Lens for Compact Housings
By Ian Bongso-Seldrup, June 25, 2018 @ 09:00 AM (EST)

After unveiling the UWL-400F wide-angle wet lens for compacts with built-in lenses that are 24mm (equivalent) at their widest, Fantasea and AOI have released another wide-angle wet lens especially designed for cameras featuring lenses that are 28mm (equivalent) at their widest.

When used with a 28mm lens, the UWL-04F provides an even wider field of view of 160 degrees (0.42X magnification), compared to the 120 degrees (0.50X magnification) of the UWL-400F, when used with a 25mm lens.

Much like the Fantasea-AOI wet lens series released in January, the new lens has a hard-anodized aluminum barrel with black hard coating, and all internal glass elements have anti-reflection coatings. The polycarbonate dome has a scratch-resistant coating. For maximum compatibility, the lens features a 52mm thread, but if your housing has a 67mm thread, you just have to use the included 52mm-to-67mm adapter.

The lens is available now and ships with cover, carrying case, secure strap, microfiber cloth, and the EyeDaptor M67-F52 lens adaptor. For local pricing, contact your authorized Fantasea dealer or email info@fantasea.com.

Fantasea and AOI Introduce UWL-04F Wide Wide Angle Lens

Available Now

The Fantasea-AOI UWL-04F is a SUPER WIDE quality "wet" wide angle conversion lens. Featuring a stunning 160-degree field of view and a remarkably short focus distance, it is perfect for all underwater wide angle compositions.

UWL-04F attaches to the housing lens port thread and can be installed and removed during the dive. The lens is compatible with most all cameras featuring a 28mm lens (or a higher focal range) and can also be used with some cameras featuring a wider lens by zooming in to avoid a vignette.

Exceptional Field of View

UWL-04F provides an FOV of 160 degrees (when used with a 28mm lens) and a magnification of 0.42X. The combination of an exceptionally wide field of view and an impressively short focus distance allows shooting breathtaking wide angle and close focus images with an inspiring angle of coverage. It is perfect for a wide variety of compositions, including seascapes, divers, ship wrecks and schools of fish, all without moving further away from the subject, thereby still taking full advantage of water clarity and artificial lighting.

Durable Construction

Lens barrel is made from a durable aluminum alloy with a black hard coating. The dome is coated as well, helping to protect it from getting scratched or damaged. During R&D, the lens was thoroughly tested in extreme conditions (depth, temperature, salinity and radiation) to ensure long term resistance and durability.

Anti-Reflection Design

The AR (anti-reflection) coating on all glass elements assists in avoiding lens flare from the sun or artificial light sources. Lens wings feature an improved design and can be rotated anytime underwater according to image composition without need of any tools. Vertical and horizontal images can be easily captured without having the sun or strobes reflecting on the dome and interfering with crystal clear images.

Universal Compatibility

The lens features a 52mm thread and can be mounted directly on any lens port with a 52mm thread or on lens ports featuring a different thread, by using a compatible adaptor. Its design allows for use with most lens holders, adaptors, bayonet mount converters, flip mounts and quick release adaptors.

The EyeDaptor M67-F52 lens adaptor is included in the box and allows mounting the lens on housings featuring a 67mm threaded lens port.

Accessory Package

Lens comes with a Neoprene dome cover and a rear lens cap for safe storage and transportation. The EyeDaptor M67-F52 lens adaptor included allows mounting the lens on housings featuring a 67mm threaded lens port. The Allen key included can be used to tighten or release the screws securing the wings to the lens, if required. The microfiber cloth can be used to clean the lens prior installation, thereby also reducing lens flare, often caused by light hitting spots on the lens.

Warranty & Best Service

The lens includes warranty against defective materials and workmanship under reasonable use for a period of 1 year. If damaged, the dome of the lens can be replaced with a new one for a discounted price during the 1-year warranty period. In addition, Fantasea offers a professional and responsive service program.
