Noob here. But no risk... Because the below is free, and I\'ll even pick up shipping via UPS inside CONUS.
LCW ( Light Craft Workshop ) 82mm Circular Polarizer and 82-to-77mm Step Down Ring
It\'s new, never used; I received it from LCW with a 2-inch long, but very narrow defect that runs along the outter edge of the glass. If you use a step down ring, I\'m sure the inclusion won\'t show up at all in your shots. LCW has already replaced it with a 77mm CPL for me, which is what I ordered, so it\'s water under the bridge at this point with them. I\'ll never use, so...
Hopefully the above pic works. (First time to post one.)
