for sale is a used, but good condition Macro 45 port for the Nauticam N85 system. This is appropriate port for a Sony A6xxx system using either a short macro or the 16-50 with any variety of wet lens. Includes the knob, which allows for zoom control on the 16-50 and I *think* focus control for macro lenses.
$520 retail. offered here for $250 plus $20 shipping.
