AOI UWL-03II Underwater 0.73× Wide Angle Conversion Lens
Expand your underwater perspective with the AOI UWL-03II Underwater 0.73× Wide Angle Conversion Lens, a premium wet lens designed to elevate action camera and smartphone footage. Built for divers and underwater content creators, this lens delivers a wider field of view, sharper imagery and consistent, professional-quality results on every dive.
Enhanced Underwater Vision
Capture more of the reef, marine life and dive action with a 140° field of view underwater, expanding to 150° on land. The wider angle allows you to stay close to your subject while fitting more of the scene into each frame.
True Wide Angle Performance
With a 0.73× magnification underwater, this lens effectively broadens your camera’s native field of view. It is well suited to wide-angle photography and videography when used with action cameras or smartphones in waterproof housings.
Precision Optics and Durable Build
The lens is constructed from 4 optical elements in 4 groups with multi-layer anti-reflective coatings to improve light transmission and reduce flare. A polycarbonate front dome with hard coating provides added durability for regular underwater use.
Easy Mounting System
The UWL-03II-BLK uses the AOI Quick Release System-02 (QRS-02), allowing fast attachment and removal underwater. It is supplied with a pre-installed QR2 mount and is also compatible with popular AD mounts via optional M55, M52 or M46 adapters (sold separately).
Built for the Deep
Rated to a maximum depth of 60 m, this lens is suitable for scuba diving and reef exploration. The anodised aluminium alloy barrel and polycarbonate hood provide strength and reliability without unnecessary bulk.
