For 28mm DC M52
AOI Lens - UWL-04 Wide Angel Lens With Dome x 0.42
In the words of the manufacturer, the AOI UWL-04 is a SUPER WIDE quality "wet" wide angle conversion lens.
Exceptional Field of View
Featuring a stunning 160-degree field of view and a remarkably short focus distance, it 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.
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.
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.
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 lens is compatible with most cameras featuring a 28mm lens (or higher focal range) and can also be used with some cameras featuring a wider lens by zooming in to avoid a vignette.
