Find of the day

This auction is for a PORST 50mm f1.2.  Even though I already own the Fujinon branded version of this lens, I want this one too.  My Fujinon is no good at 1.2 but from 2.0 to 5.6 this lens is really shines.  The seller claims the glass to be super clean.   She/he fails to mention the lens mount but more than likely it is a Fujinon-X mount.  Currently the auction is at $99 + $9.50 for shipping.
