Conversion Lenses for Underwater Macro and Wide-Angle Photography

Conversion lenses are external optics that mount onto housing ports via thread or bayonet adapters. They allow divers to change perspective from wide angle to macro within the same dive.

These add-on optics extend the capabilities of compact and mirrorless systems. Wet lenses provide both magnification for detail and extended coverage for larger underwater scenes.

Wet Macro Lenses for Close-Up Imaging

A wet macro lens increases magnification beyond what a standard flat port can provide. It reduces minimum focus distance, enabling sharp detail of small marine life and textures.

Most designs mount to M52 or M67 threaded ports. This makes them simple to attach and remove, ensuring flexible use across different underwater housing setups.

Wide-Angle Wet Lenses and Converters

Wide-angle converters expand the field of view for photographing reefscapes, schools of fish, or large structures. They help reduce distortion caused by water refraction.

Many wide-angle wet lenses use bayonet fittings for quick attachment. This allows fast switching between macro and wide-angle perspectives during a single dive.

Mounting Standards: M52 and M67 Threads

Conversion lenses are available in standard thread sizes, most commonly M52 and M67. Matching the correct thread ensures stable mounting and optical alignment with the housing port.

For even greater flexibility, conversion lenses can be mounted on flip adapters, allowing divers to swing lenses in and out of position quickly during a dive.

Adapters are also available for housings that use alternative fittings, making these lenses compatible with a wide range of systems.

  • External wet optics attach to housing ports
  • Enable macro or wide-angle imaging
  • Mount via M52 or M67 threads
  • Support both compact and mirrorless systems
  • Allow quick lens changes during a dive
