Hi
I'm selling this lightweight zoom gear for the Tokina 10-17mm (nikon mount) on nauticam housing (equivalent to #TN1017)
Not the original nauticam part, hence the cheaper price, but as solid and functional as the original (even easier to fit the gear on the lense zoon ring, in my opinion)
40 euros. Payment in USD is possible : 50 USD
You can choose your preferred option for shipping (part weight is 20grams without wrapping). Part located in Toulouse area, France
