Nauticam N85 to N120 Focus Port Extension 55 or 60 MM
This Underwater lens port adapter is for Nauticam mirrorless underwater housings like the Olympus E-M1 housing, GH5 or Blackmagic Pocket Cinema Cam. It allows you to attach larger "dSLR" size dome ports for extra-thick lenses (like the Olympus 7-14mm F2.8). It also has a focus knob that allows you to focus lenses while taking underwater video if you have the required focus gear.
