Nauticam Zoom Gear for Tokina AT-X 116 PRO DX AF 1

Zoom gear for Tokina AT-X 116 PRO DX AF 11-16mm f/2.8 lens for Nauticam Nikon DSLR housings. Replaces Nauticam TN1116-Z. Nauticam Part No.:19128 This zoom gear has a major advantage over the original Nauticam part - you don't need to remove the rubber zoom ring from the lens every time you fit the zoom gear to it. It's designed to exactly fit the groves on the zoom ring of the lens and firmly rests in place, however it's still easily mounted and removed. It can be secured with an additional rubber band if it should ever get too loose.
