Nauticam port extensions to adapt various lenses to fit one port. These lock in place with port and housing. Comes in N120 (DSLR), N100 (mirrorless) and N85 (micro 4/3rds) mount sizes. Includes cover, extra oring and silicone grease.
Went down to Cabo for a few days and then out on the Solmar V to the Soccoros for a week in mid-January. It can always be a crap shoot, and the last trip I made (this is my third) was in January and was spectacular.
