SAGA Dive is producing some more bespoke adaptors. The first one allows the use of the Nauticam WACP-1 (Ref. 85201) to Hugyfot Nikon housings. It is for use with the Nikon 28-70mm f/3.5-4.5 D.
The second is a port for the Nauticam WWL-1B that adapts it for use on Seacam housings (specifically for a GH5 Mirrorless) with the Olympus M.Zuiko Wide-Angle Zoom 14-42mm F/3.5-5.6.
SAGA also offers adaptors for the Nauticam EMWL lens with Seacam and Subal housings and for using the WACP-1 with Seacam.
