Nauticam Conversion lenses

Nauticam conversion lenses explained

In underwater photography a conversion lens is mounted in front of the port to change the optical behaviour of the primary lens. Nauticam produces several types of conversion lenses including macro lenses, wide-angle lenses and specialised optical systems. Each type is designed for a different underwater subject and shooting style. Designed for professionals and enthusiasts alike, these lenses provide clarity, color accuracy, and minimal distortion.

Macro conversion lenses for close-up subjects

Nauticam macro lenses such as the SMC and CMC series increase magnification for photographing very small marine life. These lenses are commonly used for nudibranchs, shrimp, coral polyps and other macro subjects. They can be used with compact, mirrorless and DSLR underwater camera systems depending on the port configuration.

Wide-angle conversion lenses for larger underwater scenes

Nauticam also produces wide-angle conversion lenses including models from the WWL and WACP series. These lenses increase the field of view while maintaining strong sharpness across the frame. They are used for reef scenes, wreck photography and encounters with larger marine animals.

Specialised Nauticam optics such as EMWL

The EMWL (Extended Macro Wide Lens) system combines macro magnification with a wider field of view. This optical design allows photographers to capture small subjects while still showing part of the surrounding environment.

Mounting systems and compatibility

Many Nauticam wet lenses use mounting standards such as M67 threads or bayonet mounts. This allows photographers to attach or remove the lens underwater. Nauticam lenses are designed for Nauticam housings, but several models can also be used with other underwater housings using compatible ports or adapters.

Questions about Nauticam conversion lenses

What is a Nauticam wet lens?

A Nauticam wet lens is a conversion lens mounted to the front of the port of an underwater housing. The lens can be attached or removed during a dive to change magnification or field of view.

What is the difference between SMC and CMC lenses?

The SMC series provides stronger magnification for macro photography. CMC lenses offer lower magnification and are often easier to use with compact or mirrorless camera systems.

Can Nauticam conversion lenses be used with other housings?

Some Nauticam lenses use the M67 thread standard. This makes them compatible with other underwater housings that support the same thread size or suitable adapters.
