Nauticam 0.36x Wide Angle Conversion Port (WACP) for Sigma 18-35mm

The WACP is a 0.36x Wide Angle Conversion Port.  Unlike traditional ports or wet-mate corrective wide-angle optics, the WACP is a "dry" corrective optic that modifies a 28mm equivalent lens to an extremely sharp 130º.  This version is specific for use with the versatile and fast Sigma 18-35mm F1.8 Art lens.

Focus
The WACP can focus from its front element to infinity in-water allowing for extremely close-focus wide angle shooting. When used with certain zoom lenses, the WACP can provide a variety of field-of-view options.

Buoyancy collar
An aluminum float collar is standard and brings the in-water buoyancy 0.32kg negative.
