FS: Nauticam Macroport 87 with flipholder

For Sale:  A Nauticam MacroPort 87 which is designed for use with a Nikon 105mm AF-S Micro-nikkor.  It has the Nauticam N120 port mount and is in good condition. I bought it thinking it would work with the Nikon 70-180mm Micro-nikkor which also has a 62mm front.  But it vignettes seriously at zoom settings below 110mm.  Price with the 67mm flip holder is $325.  Port alone is $225.  Flip-holder alone is $125.  Prices include shipping within USA.  If you don't have a 105mm AF-S Micro-nikkor see my listing for that lens.
