Fantasea UCL-900F +15 Super Macro Lens

Fantasea-AOI UCL-900F +15 Super Macro Wet Lens

The Fantasea-AOI UCL-900F is a premium-grade wet super macro conversion lens designed for underwater photographers who demand extreme sharpness, clarity, and magnification. With a powerful +15 diopter, it pushes close-up imaging far beyond standard macro capabilities, revealing intricate detail in the smallest marine subjects.

Engineered for professional optical performance, the UCL-900F delivers edge-to-edge sharpness with outstanding contrast and minimal distortion, making it ideal for capturing the fine textures of nudibranchs, shrimps, corals, and other tiny underwater life.

Exceptional Optical Performance

Built around a high-quality 2-group, 5-element optical design, the UCL-900F ensures consistently crisp results across the entire frame. Advanced multi-layer AR (anti-reflective) coatings on all glass surfaces reduce flare and ghosting from natural light or artificial strobes, while carefully engineered optics minimise chromatic aberration for true-to-life colour and clarity.

The +15 diopter magnification enables extremely close focusing distances, opening up creative possibilities with depth of field, framing, and subject isolation that are not achievable with standard macro setups.

Durable, Dive-Ready Construction

Housed in a robust hard-anodised aluminium body with a black protective coating, the UCL-900F is built to withstand demanding underwater environments. It has been extensively tested under extreme conditions including pressure, temperature variation, salinity, and long-term use reliability.

Rated to 60 metres / 200 feet, it is suitable for recreational, technical, and professional diving applications.

Universal Compatibility & Flexibility

Designed with a standard 67mm thread mount, the UCL-900F is widely compatible with most underwater housings and lens ports. Its slim mounting profile allows use with a range of adaptors, flip mounts, bayonet systems, and quick-release setups.

A front 67mm thread also enables stacking additional macro diopters or colour correction filters, giving photographers even more control over their imaging workflow.

Compact & Travel-Friendly Design

Despite its high optical power, the UCL-900F remains compact and lightweight at just 270g on land. Its streamlined form makes it easy to handle underwater and simple to transport, making it a practical addition to any dive photography kit.

Secure Handling & Accessories

The lens is supplied with a full accessory package designed for safe handling and protection, including:

• Front and rear protective lens caps

• Protective lens pouch

• Velcro secure strap for in-water mounting/dismounting

• Safety tether line for added security

• Microfibre cleaning cloth

The secure strap system allows the lens to be attached or removed during a dive without detaching it from the housing system, ensuring both convenience and safety.
