0.36x Wide Angle Conversion Port Set with Aluminum Float Collar for Sigma 18-35mm F1.8
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.
