IKELITE DLM 2 INCH PORT EXTENSION
With IKELITE DLM 2 INCH PORT EXTENSION, you can increase the length of select ports in order to accommodate longer lenses. The accessory is compatible with the 5516.45 Flat Port for Panasonic's 12-60mm f/3.5-5.6 ASPH Power OIS lens, as well as the 5516.50 Flat Port for the Olympus M.ZuikoDigital ED 12-100mm f/4 IS Pro. Additionally, it can be used with the 5516.15 Dome Port for Sony's FE 24-70mm f/4 ZA OSS Zeiss Vario Tessar T* lens. Optional equipment may be required for lens compatibility.
It's easy to remove the port from your underwater camera housing and attach the extension in its place. Once done, simply slide the port back on over the extension.
