I've got a 67mm Hoya HMC Circular Polarizer, which was used on a lens that I previously had but recently sold. I no longer have a lens with a 67mm filter size. That said, I need a filter for my Sigma 17-70, which is 72mm.
Does anyone want to trade their 72mm CPL for my 67mm? It's in excellent condition with no scratches, and I would expect yours to be similar in condition and quality. PM if interested!
